Mendix & Agile: When Low-code is More Than Just "Drag-and-Drop"

In the development world, Mendix is often discussed as a tool for rapid application building. However, that speed doesn't just come from reducing lines of code; it stems from its perfect integration with the Agile methodology. If you consider Low-code the engine, then Agile is the steering system that keeps the project on track.

1. Breaking the "Waterfall" Prejudice

source: https://academy.mendix.com/index3.html#/lectures/3136

Many software projects fail not because of poor code, but due to the rigidity of the Waterfall process. In a rapidly changing market, fixing the scope at the very beginning is a massive risk.

Agile in Mendix inverts the traditional project management triangle:

  • Fixed Resources and Time: You know exactly what you have and how long a Sprint lasts—typically two weeks.

  • Flexible Scope: Instead of doing everything halfway, the team focuses on completing the most valuable features to deliver a working product after every cycle.

2. Agile Mindset: Living with Change

Being Agile is less about the mechanics and more about the Agile Mindset. For a Mendix Developer, this mindset boils down to three principles:

  • Small and Focused: Breaking work into smaller pieces (User Stories) increases focus and enables quick results.

  • Feedback is a Gift: It is better to fail early and fix early than to receive negative feedback after the project has ended.

  • Ownership: In an Agile team, there is no "micro-manager." Every member takes initiative and responsibility for their own tasks.

3. Team Structure: Core Team and Experts

Mendix optimizes development through cross-functional teams:

source:https://academy.mendix.com/link/modules/390/The-Agile-Methodology

    • Core Team: Consists of the Product Owner (vision manager), Scrum Master (process guardian), and 2-3 Business Engineers (the ones building the app).

    • Subject Matter Experts (SMEs): Experts in UX/UI, Security, or Integration "fly in" when a Sprint requires deep specialized knowledge and leave once the task is complete.

4. Realizing Agile with Mendix Tools

Mendix doesn't just keep Agile on paper; the platform provides powerful execution tools:

source: https://academy.mendix.com/link/modules/390/The-Agile-Methodology

  • Epics & User Stories: Manage the backlog and roadmap directly on the Portal using the standard structure: "As a... I want... so that...".

  • Feedback Widget: This is the direct bridge between users and developers. Feedback is sent straight to the Portal for the PO to evaluate and include in the next Sprint.

  • Lean Thinking: Leveraging Reusable Components reduces waste and allows the team to focus on creating new value.

5. The Roadmap to Digital Execution Success

To maximize the effectiveness of a Mendix project, you should follow a 5-step roadmap:

  1. Understand the Context: Know exactly why the project needs Agile.

  2. Establish the Mindset: Build trust and transparency within the team.

  3. Define Roles Clearly: Ensure everyone understands their authority and responsibilities.

  4. Sprint 0: Prepare infrastructure, design wireframes, and align goals before coding begins.

  5. Execute and Improve: Build while reflecting to optimize performance continuously.

Conclusion: Developing on Mendix without Agile is like having a supercar but driving it on a road full of potholes. Combine the power of Low-code with the flexibility of Agile to create truly breakthrough products.

ECR, ECS, vs EKS: Understanding AWS Containers

In the era of modern software development, packaging applications with Docker is just the beginning. When you have dozens or even hundreds of Microservices that need to run concurrently, auto-recover from failures, and scale in an instant, you need Container Orchestration tools.

In the AWS ecosystem, this challenge is perfectly solved by a trio of services: Amazon ECR (Storage), alongside two orchestration options, Amazon ECS and Amazon EKS. Understanding and choosing the right "conductor" will determine the success of your infrastructure architecture.

1. Amazon ECR (Elastic Container Registry): The Secure "Vault"

Before containers can run, they need a secure place to be stored. ECR is a fully managed container registry by AWS, similar to Docker Hub but tailored for the enterprise ecosystem.

  • Enterprise-Grade Security: Deeply integrated with AWS IAM. You can grant granular permissions down to each repository (e.g., Server A can only "pull", Developer B can "push").

  • Automated Image Scanning: ECR automatically scans for software vulnerabilities (CVEs) whenever a new image is pushed—a mandatory feature for healthcare (HIPAA compliant) or financial systems (PCI-DSS compliant).

  • Speed & Optimization: Thanks to AWS's internal network infrastructure, pulling images from ECR to ECS or EKS happens with near-zero latency.

Once images are ready on ECR, we face a crossroads: Should we choose ECS or EKS to run them?

2. Amazon ECS (Elastic Container Service): Simple, Fast & Optimized for AWS

ECS is the "native" container orchestration solution developed by AWS. The philosophy of ECS is to deliver maximum simplicity for users operating within the AWS ecosystem.

  • Low Learning Curve: If your team lacks Kubernetes experience, ECS is the perfect choice. Concepts like Task Definitions and Services in ECS are very straightforward to grasp.

  • Deep Integration: The biggest strength of ECS is its seamless cohesion with other AWS services (ALB, Route 53, CloudWatch, IAM).

  • The Power of AWS Fargate: Both ECS and EKS support Fargate (Serverless compute for containers), but the Fargate experience on ECS is significantly smoother and more seamless. You simply deploy the container, and AWS handles the entire underlying infrastructure.

3. Amazon EKS (Elastic Kubernetes Service): Unmatched Power & Industry Standard

If ECS is an easy-to-drive automatic car, EKS is an F1 racing car with countless customizable buttons. EKS is a managed Kubernetes (K8s) service—the open-source platform that currently serves as the global "gold standard" for container orchestration.

  • Massive Ecosystem: K8s boasts the largest open-source community. Thousands of tools (Helm, Prometheus, Istio, ArgoCD) are natively designed to run on K8s.

  • No Vendor Lock-in: Because EKS is fundamentally standard Kubernetes, you can easily "lift and shift" your entire system from AWS to Google Cloud (GKE), Azure (AKS), or even run it on physical servers (On-premise) without rewriting extensive configurations.

  • Maximum Flexibility: EKS allows you to deeply customize network configurations (Custom CNI), schedule containers (Advanced Scheduling), and manage complex resources.

4. Comparison Table: ECS vs. EKS

To easily visualize the differences, here is a quick comparison between the two services:

 Criteria  Amazon ECS  Amazon EKS
 Core Technology  AWS Proprietary  Open-source platform (Kubernetes)
 Complexity  Low - Easy to learn and operate  Very High - Requires specialized DevOps team
 Ecosystem  Integrated with AWS native tools  Massive open-source ecosystem (CNCF)
 Vendor Lock-in  High (Hard to migrate to other clouds)  Low (Easy to migrate across Multi-cloud/On-premise)
 Control Plane Cost  Free (Pay only for compute resources used)  ~$73/month per EKS Cluster
 Best Suited For  Startups, fast-to-market projects, AWS-centric teams  Large enterprises, Hybrid Cloud, Multi-cloud systems

 

5. Real-World Scenarios from ISB Vietnam

At ISB Vietnam, choosing an architecture depends entirely on the client's business problem:

  • Scenario 1 (Choosing ECS): An internal Business Management System needs rapid modernization from legacy to Cloud. The client wants the lowest maintenance costs, and their IT team has no K8s experts. Solution: ISB Vietnam consults using ECR + ECS Fargate. The infrastructure is spun up in days, auto-scales during business hours, and scales to zero at night to save costs.

  • Scenario 2 (Choosing EKS): A MedTech corporation needs to build a global wearable device data collection platform. A strict requirement is that the system must run partly on AWS and partly on the hospital's physical Data Center to comply with local data residency laws. Solution: ISB Vietnam utilizes EKS combined with Amazon EKS Anywhere. Kubernetes provides absolute consistency between Cloud and On-premise environments, while allowing the deployment of complex Service Mesh tools to encrypt healthcare data.

Key Takeaways

  • ECR: The secure vault for your Docker Images with built-in vulnerability scanning.

  • ECS: Optimized for speed and simplicity. Choose ECS if you want to focus on application code rather than managing infrastructure.

  • EKS: The industry standard. Choose EKS if your system is highly complex, requires multi-platform capabilities (Multi-cloud), and you have a robust DevOps team.

What's Next?

Both ECS and EKS are powerful, but they truly shine when deployed entirely via automation (Infrastructure as Code). In our next post, we will explore how to use Terraform to spin up these entire ECS/EKS clusters with just a single line of code.

In your organization, is your technical team leaning towards the "simplicity and ease of management" of ECS, or the "global standardization" of EKS? Share your system challenges in the comments below so we can discuss!

How RAG Works: Lessons from a Junior Developer

Recently, while working on a project, I had the chance to explore how a Retrieval-Augmented Generation (RAG) system works. Before that, I mostly interacted with Large Language Models through APIs, without thinking too much about how they actually retrieve and use external information.

With the rapid development of LLMs, many people have begun asking AI questions rather than searching on Google. This is very convenient, but LLMs have an important limitation: They can only answer questions based on the data they have been trained on.

For example, if a model was trained in 2025, how will it know what happens in 2026? If we want it to respond with information from documents it has never seen before, how will it know?

That's why RAG systems come in. This article is the first part of a short series documenting what I learned while trying to build a RAG system locally.

The series is divided into three parts:

  • Part 1 - Understanding the RAG Pipeline.
  • Part 2 - Running RAG locally.
  • Part 3 - Challenges and lessons learned.

In this first part, we’ll walk through the basic architecture of a RAG system and understand how its main components work together.

Simplified RAG pipeline

Instead of relying only on what the model already knows, RAG allows the model to retrieve relevant information from external documents.

Although many variations of RAG architectures exist today, most of them revolve around three core components: Document ingestion, retrieval, and generation.

Document Ingestion

The first step in a RAG system is preparing the documents so the system can use them.

Document Parsing

The main job of a parser is to extract text from documents such as PDFs, Word files, or HTML pages. Currently, many tools support this: Docling (Python), Langchain Document Loader (Python/TypeScript), Apache Tika (Java), etc.

Text chunking

At its most basic, we can segment by chunk size. Why do we need to chunk? LLMs have a limited context window and cannot process an entire document at once. Just as we can't remember the entire contents of a file.

For example, a chunk size of 100 means splitting the document into smaller chunks of 100 characters each. More complex methods involve segmenting based on the document's structure and layout.

In practice, chunking strategies may vary depending on the document structure and the context window of the language model.

Document
┌───────────────────────────────┐
Employee Handbook
Employees must reset their passwords every 90 days.
Passwords must contain at least 8 characters.
Two-factor authentication is recommended.
└───────────────────────────────┘

                ↓
            Text Chunking

Chunk 1                  Chunk 2                  Chunk 3
┌────────────────┐   ┌────────────────┐   ┌────────────────┐
Employees must   │   │Passwords must  │   │Two-factor      │
reset passwords  │   │contain at      │   │authentication  │
every 90 days    │   │least 8 chars   │   │is recommended  │
└────────────────┘   └────────────────┘   └────────────────┘

Embedding

Since machines process numbers rather than raw text, we have to convert letters into numbers for them. Embedding is the process of converting text into vectors using an embedding model. These vectors allow the system to measure semantic similarity between the user query and document chunks.

Chunk 1
"Employees must reset their passwords every 90 days."
↓
Embedding
[0.21, -0.33, 0.81, 0.45, -0.12, ...]

Vector Database

After the embeddings are generated, they are stored in a vector database. Unlike traditional databases that store structured data, vector databases are designed to store vector representations and efficiently perform similarity searches. Once all document chunks are stored in the vector database, the system is ready to retrieve relevant information when a user asks a question.

Retrieval

This is the core of RAG technology. Instead of searching text traditionally, the system searches for document vectors that are closest to the query vector of the user query.

Query Embedding

Similar to the previously vectorized document chunks, when a user submits a question, that question will also be converted into a vector.

Always remember this: both query embedding and chunk embedding must use the same embedding model.

User Question:
How often should employees reset their passwords?

↓
Embedding
[0.18, -0.41, 0.72, ...]

Vector Search

To put it simply, imagine that all document embeddings are points in a multi-dimensional space. When a user asks a question, the query is also converted into a vector and placed in the same space. The system then searches for document vectors that are closest to the query vector.

But what do we mean by “closest”?

In practice, similarity between vectors is measured using mathematical metrics such as cosine similarity or dot product. These metrics help the system identify document chunks that are semantically similar to the user's question.

Top-k Relevant Chunks

The top-k retrieved chunks are then combined and sent to the LLM as context. The exact value of k can vary depending on the system and the model’s context window.

In simple terms, the system gives the model relevant pieces of text and asks it to answer the question based on that information.

Query:
"How often should employees reset their passwords?"

↓

Top-k Retrieved Chunks

┌──────────────────────────────┐
Chunk 12
Employees must reset passwords
every 90 days.
└──────────────────────────────┘

┌──────────────────────────────┐
Chunk 27
Passwords must contain at least
8 characters.
└──────────────────────────────┘

┌──────────────────────────────┐
Chunk 35
Two-factor authentication is
recommended for all accounts.
└──────────────────────────────┘

↓

Context sent to LLM

↓

Answer

Generation

Now it's time to ask this AI a question. This step works similarly to copying text from somewhere, giving it to the AI, and asking, "Hey, what's in here?”

Prompt Construction

Besides the retrieved context, we also need to provide the LLM with a clear instruction. A simple prompt structure usually contains the context, the user’s question, and an instruction telling the model to answer based only on the provided information. Something like this:

You are an assistant who answers questions based on the provided context.

Context:
Employees must reset their passwords every 90 days.
Passwords must contain at least 8 characters.
Two-factor authentication is recommended.

Question:
How often should employees reset their passwords?

Answer:

LLM will automatically fill in the answer.

Context - Question - Answer Generation

This is the final step of the RAG process. This step is simple: after the LLM receives the prompt and context, it uses that information to answer the question. This process helps reduce hallucinations by grounding the answer in retrieved documents. commonly seen in LLMs.

However, there is one important thing to note. The accuracy of the answer depends on two factors:

  • Was the previous document search step correct? If you give it the wrong information, of course, it will give the wrong answer.
  • Is LLM strong enough? Even large models have a limited context window, so the system must carefully choose how many chunks to include.

Key Takeaways

  • Retrieval-Augmented Generation (RAG) enables LLMs to answer questions using external documents rather than relying solely on training data.
  • The documents must undergo a process of being received and encoded as vectors before they can be used.
  • A vector database is where vectors are stored and searched.
  • When a user asks a question, the system retrieves the most relevant document segments within the database.
  • The retrieved chunks are then combined into context and sent to the LLM to generate the final answer.

What’s next?

In this article, we walked through the basic pipeline of a RAG system — from document ingestion to answer generation.

In Part 2 - Running a RAG system locally, I’ll share what happened when I tried to run a RAG system locally, including the tools I used and some practical limitations I encountered during development.

This article is part of a technical blog series from ISB Vietnam, where our engineering team shares practical insights and lessons learned from real-world projects.

Why Your AI Is Only As Good As Your Prompts

I. The Trust Gap

     GenAI tools, such as ChatGPT, Claude, and Google Gemini have an immense potential to improve our quality of life and help out with a lot of global issues. Yet, there is a fairly strong and widely discussed consensus that GenAI can be inaccurate.

     A recent KPMG survey[1] with over 48,000 people globally shows that even though 66% of them use GenAI regularly, only 46% felt willing to trust AI systems. It’s because many people are relying on GenAI output without evaluating its accuracy, which led to mistakes in their work.

     In my opinion, the problem is often not the technology itself, but the way it’s being used. GenAI, without a doubt, is incredibly powerful, but the quality of its output depends heavily on the quality of the prompt users provide. Learning how to create a clear, specific, and well-structured command or request when working with GenAI is the key to unlock these tools real potential.

 

 

II. What is prompt Engineering?

     Prompt Engineering is the essential skill of designing and refining prompts to improve the output of GenAI systems. Because GenAI models respond based on the specific input they receive, a well-structured prompt allows you to:

  • Produce more detailed and relevant responses.
  • Significantly improve output accuracy.
  • Control the format and style of the final result.

 

 

III. Prompt Engineering Techniques.

     Now that we understand what Prompt Engineering is, let’s break down some of the widely used techniques to craft prompts[2].

1. Zero-Shot Prompting:

          This is a technique where you present a task to the AI model without providing any examples or task-specific demonstrations. Its accuracy relies heavily on the strength of the underlying foundation model. The more advanced and capable the foundation model, the more likely the AI is to produce accurate results.

          Zero-shot prompting is often more suitable for straightforward tasks or when a quick response is needed, even though it can still handle more complex tasks with varying reliability.

 

2. Few-Shot Prompting:

          This technique involves providing a few examples within the prompt to guide the AI’s output. Instead of training the model, you guide it during inference by providing specific contextual examples (input-output pairs).

          If you provide the AI with only one example, then this technique is also called “Single -shot” or “One-Shot Prompting”.

 

 

3. Chain-of-Thought (CoT) Prompting:

          This is a technique where you break a task into a sequence of intermediate reasoning steps. This helps the AI model process logic more effectively, leading to more structured and accurate results. You can trigger this by providing examples of step-by-step reasoning or by simply adding instructions like “Break this into steps”.

          However, CoT prompting should be used selectively, mainly for tasks that require multi-step reasoning, where accuracy matters more than speed. In simpler cases, forcing step-by-step reasoning may slow the AI down or introduce unnecessary verbosity.

 

 

IV. Conclusion

     GenAI effectiveness depends largely on how it is used. Rather than viewing them as unreliable, It’s more productive to see AI as a tool that requires skill and thoughtful interaction.

     Mastering AI communication is becoming an essential skill in today’s digital world. By crafting clear and structured prompts, users can unlock the full potential of GenAI and use it more confidently and responsibly in their work and daily lives.

     If you're eager to take your Prompt Engineering skill to the next level and apply them to impactful, real-world projects, ISB VIETNAM offers an environment where Passions, Teamwork, Innovations, and continuous learning are part of our everyday work. Visit the official website now to learn more about our company services, and how you can become part of a team that values thoughtful, high-quality software engineering.

Microsoft 365 Login with ExpressJS

Identity is one of the most important security layers of modern systems. Modern apps must connect to numerous services, making a centralized and stable login system essential.

In this context, Microsoft 365 login is a logical choice for enterprise systems. Azure provides a standardized identity platform, eliminating the need to build authentication mechanisms from scratch.

Overall

At the high level, ExpressJS only acts as the client. Azure AD is the main entity, acting as the identity provider. The browser only handles redirects, while all sensitive processing, such as exchanging code for tokens, takes place in the backend.

The basic flow would be:

User → ExpressJS → Microsoft login → ExpressJS callback → session creation

Most importantly, the token never appears on the frontend. This is extremely important from a security perspective.

Setting up Azure AD

First, create a new application in Azure Active Directory via the Azure Portal.

Then create a Client Secret. Simply put, this is the "password" for the backend.

Finally, we will have three values; these three are the backbone of the entire login process:

  • Client ID – app identifier
  • Tenant ID – organization identifier
  • Client Secret – backend authentication

MSAL node configuration

Microsoft provides @azure/msal-node so developers don't have to manually code OAuth2. MSAL handles the headaches of code generation, token changes, token caching, and token refresh.

Installation:

npm install express @azure/msal-node express-session dotenv

Basic configuration:

// msalConfig.js

require("dotenv").config();

module.exports = {

    auth: {

        clientId: process.env.CLIENT_ID,

        authority: "https://login.microsoftonline.com/" + process.env.TENANT_ID,

        clientSecret: process.env.CLIENT_SECRET

}};

The Authority URL simply tells MSAL which tenant we are authenticating with.

After defining the config, we will create the other file to initialize the instance to use in the project

// msalClient.js

const { ConfidentialClientApplication } = require("@azure/msal-node");
const msalConfig = require("../config/msalConfig");

const cca = new ConfidentialClientApplication(msalConfig);

module.exports = cca;

Scope: Request only what we need

Scope refers to access permissions. It determines what the app can do on behalf of the user.

Here are some common scopes:

  • user.read – read basic profiles
  • mail.read – read email
  • files.read – read OneDrive files

The first time a user logs in, they will see a consent screen. This is very good, as it helps them know what permissions the app is requesting.

Actual login flow

Here, we use the OAuth2 authorization code flow – almost the default standard for backends.

The token is not exposed to the frontend. There is a refresh token widely accepted by enterprises

Route /login

const cca = require("./services/msalClient"); 

app.get("/login", async (req, res) => {

   const url = await cca.getAuthCodeUrl({

     scopes: ["user.read"],

     redirectUri: "http://localhost:3000/redirect"

    });

   res.redirect(url);

 });

This route only serves to redirect the user to the Microsoft login page.

Note: The redirectUri in the code must match the Redirect URI declared in Azure AD.
If they don't match, the login will fail.

Route /redirect

const cca = require("./services/msalClient"); 

app.get("/redirect", async (req, res) => {

   const tokenResponse = await cca.acquireTokenByCode({

     code: req.query.code,

     scopes: ["user.read"],

     redirectUri: "http://localhost:3000/redirect"

   });

   req.session.user = tokenResponse.account;

   req.session.accessToken = tokenResponse.accessToken;

   res.redirect("/dashboard");

 });

This is the main processing point: the backend exchanges the code for a token and then saves the session.

Sessions and Middleware

After establishing the session, protecting the route with middleware is all we need to do.

 function requireAuth(req, res, next) {

   if (!req.session.user) {

     return res.redirect("/login");

   }

   next();

 }

Conclusion

Microsoft 365 login is becoming the standard for modern enterprise systems. Instead of managing users, passwords, and complex security rules ourselves, we can directly use Azure Active Directory as a trusted identity provider.

In practice, this offers better security, less maintenance, and a login system that can scale across the organization without significant changes.

Mastering Burp Suite: Are you really getting the most out of it for your web security testing?

In the world of software testing, if automation tools ensure that a system works, then Burp Suite ensures that the system cannot be broken. As we move further into the era of complex architectures like UI-BFF-API, simply checking features is no longer enough. To truly level up your career, you must master the gold standard of security testing: Burp Suite.

But what makes this tool so indispensable? Let’s dive into its most effective applications.

  1. The Core Power: Intercepting Proxy

The most effective and fundamental application of Burp Suite is its Intercepting Proxy.

How it works: Burp Suite sits between your browser and the server. When you click Submit, Burp catches the request. This allows you to pause, inspect, and modify the data before it ever reaches the server. Why is this a "Game Changer" for Testers?

  • Bypassing Front-end Validation: You can bypass UI restrictions (like disabled buttons or character limits) to see if the Server-side is truly secure.
  • Parameter Tampering: Have you ever wondered what happens if you change a product price from $1,000 to $1 during checkout? With the Proxy, you can test this in seconds.  
  • Broken Access Control: In a multi-site system (Candidate, Parent, Admin), you can swap authorization tokens to see if a Parent can sneak into the Admin panel.

  1. Top 3 Features to Supercharge Your Testing

Beyond intercepting traffic, Burp Suite offers specialized modules that act like superpowers for a QC:

  • Repeater: Unlimited Experimentation

Instead of re-loading the web page and re-filling forms, Repeater allows you to send the same request over and over with different modifications. It’s the fastest way to pinpoint logic flaws and edge cases.

  • Intruder: Automated Attacks

Need to test 1,000 different password combinations? Or check for IDOR (Insecure Direct Object Reference) by cycling through 500 different User IDs? Intruder automates these repetitive tasks, saving you hours of manual work.

  • Scanner (Pro Version): Automated Vulnerability Detection

For busy QCs, the Scanner automatically crawls the application to find common vulnerabilities like SQL Injection, XSS, and Security Misconfigurations while you focus on more complex testing scenarios.

  1. Applying Burp Suite to the UI-BFF-API Model

In your daily work with the UI-BFF-API architecture, Burp Suite becomes a surgical tool:

  • Testing the BFF Layer: Ensure that the Backend-for-Frontend is properly filtering sensitive data before sending it to the UI.
  • Role-Based Testing: With four distinct sites (Candidate, Parent, University Admin, System Admin), Burp makes it easy to manage multiple sessions and ensure that users stay within their permitted boundaries.

      1. Tips for Junior QCs Starting with Burp Suite

      Don’t let the complex interface intimidate you. Here is how to start:

      • Learn Proxy Configuration first: This is your gateway to understanding how the web talks.
      • Monitor the HTTP History: Simply observing the flow of requests and responses will teach you more about web architecture than any textbook.
      • Ethics First: Always use Burp Suite in a staging/UAT environment. Never use it on a production system without explicit permission.

      Would you like me to create a Quick Start Guide for configuring Burp Suite with your UI-BFF-API application?

      To test an architecture consisting of an Exam Candidate, Parent, and Admin sites, you need to see exactly how the UI talks to the BFF (Backend-for-Frontend).

      Step 1: The Basic Connection (The Proxy)

      1. Launch Burp Suite: Open the application and select Temporary Project.
      2. Use the Built-in Browser: Go to the Proxy tab > Interceptor sub-tab > Click Open Browser. 
        • Why? This is much easier than configuring Firefox or Chrome manually, as Burp handles the SSL certificates for you automatically.
      3. Turn Intercept off: For now, keep it off so you can browse the sites freely while Burp records the history in the background. 

        Step 2: Organize Your Scope (Crucial for 4 Sites)

        Since you are working with four different sites, your history will get messy quickly.

        1. Go to the Target tab > Scope sub-tab.
        2. Add the URLs of all four sites (e.g., https://candidate.example.com, https://admin.example.com).
        3. Go to the Proxy tab > HTTP History.
        4. Click the Filter bar at the top and check Show only in-scope items.
          • Result: You will now only see traffic related to your project, hiding background noise like Windows updates or Google analytics.

        Step 3: Mapping the UI-BFF-API Flow

        1. Open your Candidate Site in the Burp Browser and perform a Login.
        2. Look at the HTTP History. You will see a request going from the UI to the BFF.
        3. The Secret Sauce: Right-click that Login request and select Send to Repeater.
        4. In Repeater, you can now manually change the username or password and hit Send to see how the BFF responds without re-typing anything in the browser.

        Step 4: Testing Roles (The Parent vs. Admin Test)

        This is the most effective test for your specific architecture:

        1. Log in as a Parent in the browser.
        2. Find a request in the history that fetches Parent Data from the BFF. Look for the Authorization: Bearer <TOKEN>
        3. Now, try to access an Admin API URL by pasting it into the Repeater.
        4. If the BFF returns 200 OK instead of 403 Forbidden, you've found a Critical Security Bug!

        Finally, if AI is the assistant that helps you write test cases faster, Burp Suite is the microscope that helps you find the invisible bugs that could destroy a company’s reputation. By mastering Burp Suite, you transition from a standard Tester to a Security-Aware Quality Engineer.

        When Should You Use ADO.NET vs Entity Framework?

        When developing applications with the .NET platform, developers often face a common question: Should we use ADO.NET or Entity Framework for database access? Both technologies are widely used in the .NET ecosystem and each has its own strengths. Choosing the right one can significantly impact performance, maintainability, and development speed. In this article, we’ll explore the differences and discuss when you should use ADO.NET and when Entity Framework is the better choice.

        Understanding ADO.NET

        ADO.NET is the traditional data access technology used in .NET applications. It provides low-level access to databases and requires developers to write SQL queries manually.

        Typical components include:

        • SqlConnection
        • SqlCommand
        • SqlDataReader
        • DataTable
        With ADO.NET, developers have full control over how queries are executed and how data is retrieved.

        Advantages of ADO.NET

        • ✅ High performance
        • ✅ Full control over SQL queries
        • ✅ Suitable for complex database operations

        Disadvantages

        • ❌ More boilerplate code
        • ❌ Manual mapping between database tables and objects
        • ❌ Harder to maintain in large applications

        Understanding Entity Framework

        Entity Framework (EF) is an Object-Relational Mapper (ORM) developed by Microsoft.

        Instead of writing SQL queries, developers interact with the database using C# objects and LINQ queries.

        Example:

        var users = context.Persons.Where(u => u.Age > 18).ToList();

        Entity Framework automatically converts this into SQL and executes it against the database.

        Advantages of Entity Framework

        • ✅ Faster development
        • ✅ Cleaner and more readable code
        • ✅ Automatic object-relational mapping
        • ✅ Strong integration with LINQ

        Disadvantages

        • ❌ Potential performance overhead
        • ❌ Less control over generated SQL
        • ❌ Not always optimal for complex queries

        When Should You Use ADO.NET?

        1. When Performance Is Critical

        If your application processes large volumes of data or requires extremely optimized queries, ADO.NET is often the better choice. Examples:
        • Financial systems
        • High-traffic enterprise applications
        • High-traffic enterprise applications
        • Batch processing systems
        Because SQL is written manually, developers can optimize queries precisely.

        2. When Working with Complex Queries or Stored Procedures

        Some database operations involve:
        • Advanced joins
        • Complex stored procedures
        • Custom indexing strategies
        ADO.NET allows developers to execute and optimize these queries directly.

        3. When Maintaining Legacy Systems

        Many older .NET applications were built using ADO.NET.

        If you are maintaining or extending an existing system, continuing to use ADO.NET may be more practical than refactoring everything to an ORM.

        When Should You Use Entity Framework?

        1. When Rapid Development Is Important

        Entity Framework significantly reduces the amount of code needed for common operations.

        It is ideal for:

        • Web APIs
        • Internal business applications
        • Startup or MVP projects
        Developers can focus on business logic rather than SQL queries.

        2. When Your Application Has a Strong Domain Model

        If your application contains many business entities like:

        • Users
        • Orders
        • Products
        • Invoices
        Entity Framework helps map these entities directly to database tables, making the architecture more intuitive.

        3. When Maintainability Is a Priority

        Entity Framework improves:

        • Code readability
        • Maintainability
        • Developer onboarding

        New developers can understand the system faster because the code closely reflects the domain model rather than raw SQL.

        Best Practice: Use Both

        In many modern projects, teams combine both approaches.

        A common strategy is:

        • Entity Framework → for standard CRUD operations
        • ADO.NET or raw SQL → for performance-critical queries

        This hybrid approach balances development productivity and performance optimization.

        Conclusion

        There is no one-size-fits-all solution.

        • Use ADO.NET when performance and SQL control are critical.
        • Use Entity Framework when you want faster development and easier maintenance.

        Understanding when to use each technology will help you design scalable, efficient, and maintainable .NET applications.

        Implementing Access Tokens and Refresh Tokens "The Right Way"

        Implementing Access Tokens and Refresh Tokens is the gold standard in modern authentication (especially with JWT - JSON Web Tokens). The goal is to balance security and user experience.
        Below is a detailed guide on how to use these two token types "correctly" and most securely.

        1. Why do we need 2 types of tokens?

        Why not use a single token with a permanent expiration? Because if a hacker obtains that token, they gain access forever. We split them into two to minimize risk:
        Feature
        Access Token (AT)
        Refresh Token (RT)
        Purpose
        Access resources (API)
        Request a new Access Token
        Lifespan
        Very short (15 minutes - 1 hour)
        Long (7 days - 30 days)
        Storage Type
        Stateless (usually JWT)
        Stateful (stored in DB/Redis for control)
        Risk
        If lost, the hacker can only use it for a short time
        If lost, consequences are more serious (but it can be revoked)

        2. Standard Workflow (The Flow)

        Here is the standard lifecycle of this authentication mechanism:
        1.Login: User sends User/Pass. Server authenticates and returns an AT and RT pair.
        2.Storage: Client stores AT and RT in a secure place (see section 3).
        3.Send Request: Client sends a request with AT in the Header (Authorization: Bearer <token>).
        4.Expired:
        - Server checks AT. If expired -> Returns 401 Unauthorized error.
        -  Client receives 401 error -> Automatically sends a /refresh-token request with RT to the Server.
        5.Renewal:
        * Server checks RT (is it valid? is it blacklisted?).
        * If valid -> Server returns a new AT (and usually a new RT - see Token Rotation section).
        6.Retry: Client uses the new AT to retry the original request without the user realizing it happened.

        3. Storage "Best Practices"

        This is the most important part to avoid security vulnerabilities (XSS and CSRF).

         A. For Web Applications (SPA - React, Vue, Angular)

        The common way is to save to `localStorage`, but the safest way is:

         

        Access Token: Store in JavaScript local variable (in-memory).
        Pros: XSS attackers cannot read the token (because it is not in storage).
        Cons: Token is lost when the page is refreshed (F5) (solved by silently calling a refresh token API immediately upon page load).

         

        Refresh Token: Store in HttpOnly Cookie.
        Cookie configuration: HttpOnly (JS cannot read), Secure (sent only over HTTPS), SameSite=Strict.
        Pros:* Completely immune to XSS. Hackers cannot copy this token.

         

        B. For Mobile Apps (iOS/Android)

        Store both in the operating system's secure storage.
        iOS: Keychain.
        Android: EncryptedSharedPreferences / Keystore.

        4. Token Rotation Mechanism

        To enhance security, you should not use the same Refresh Token forever. Use the Refresh Token Rotation technique:

        1. Every time the Client uses Old_RT to request a new token.
        2. The Server will return New_AT and New_RT.
        3. The Server marks Old_RT as used (or deletes it) in the Database.
        4.Theft Detection: If a hacker steals Old_RT and tries to use it to refresh -> The Server sees that Old_RT has already been used -> The Server immediately revokes all RTs related to that user, forcing the user to log in again.

        Conclusion

        1. Access Token short, Refresh Token long.
        2. Web: Prioritize HttpOnly Cookie for Refresh Token, In-memory for Access Token.
        3. Mobile: Use Keychain/Keystore.
        4. Backend: Always validate Refresh Token in the database (to allow revocation/revoke when needed).
        5. Rotation: Change to a new Refresh Token after every use.

        OUTSOURCING

        March 16, 2026

        DevOps Best Practices: What to Build and What to Outsource

        DevOps can speed up releases and improve reliability, but many mid-sized teams get stuck. Tooling is inconsistent, environments drift, incidents are handled reactively, and delivery slows down as systems grow. When you do not have dedicated SRE or DevOps specialists, the challenge is not knowing what to implement first, and what you can safely hand off to a partner.

        Fueled by digital transformation, the DevOps outsourcing market is surging as organizations seek to manage complex cloud-native environments, address talent gaps, and accelerate their time-to-market. According to Future Market Report (2025), the market is valued at approximately USD 12.5 billion and is projected to reach USD 28.4 billion by 2032, growing at a CAGR of 10.8%. North America leads with a 35.6% market share, with the U.S. accounting for the largest single-country portion at 22.1%.

        This guide breaks down DevOps best practices that work in real projects. We clarify the minimum deliverables to aim for, how to split responsibilities between in-house and outsourced teams, and the common failure patterns that derail DevOps efforts. You will also learn what drives cost, which engagement model fits your situation, and how to evaluate a DevOps partner before you commit.

        What DevOps Means in Practice

        devops best practices

        In real projects, DevOps is not a philosophy deck. It is an operating system for how your team builds, tests, secures, and delivers software.

        For companies running web services or internal platforms, DevOps typically includes:

        • A standard CI pipeline used by every developer
        • Infrastructure as code to control environment drift
        • Automated testing and deployment
        • Monitoring tied to business impact
        • Defined ownership and incident response

          The key shift is control. You move from reactive issue handling to a structured, measurable delivery model.

          Why DevOps Matters for Mid-sized Teams

          devops best practices

          For mid-sized organizations, the business impact of slow delivery is now measurable. A 2025 TechRadar Pro report found that software projects are delayed by an average of four months, costing companies approximately £107,000(around USD 135,000) per year due to missed opportunities and inefficiencies. The report emphasizes that executives increasingly view sluggish delivery as a strategic liability that directly affects competitiveness and revenue growth.

          At the same time, DevOps is expanding beyond traditional application delivery. Another 2025 TechRadar Pro article highlights that 85% of machine learning models never make it into production, largely due to fragmented processes between development, operations, and data teams. This statistic underscores the growing need to unify DevOps and MLOps into a single, end-to-end software supply chain.

          Together, these figures reinforce that modern DevOps is not just about faster releases. It is about reducing measurable business loss and ensuring that innovation actually reaches production.

          DevOps Best Practices That Actually Work

          devops best practices

          DevOps works best when it combines reliable processes, automation, and a culture of ownership. The practices below show how mid-sized teams can build a delivery system that is fast, secure, and scalable.

          Build the CI and Release Path (CI/CD)

          A consistent CI/CD workflow is the foundation of reliable delivery. Every change should flow through an automated pipeline from commit to production, ensuring builds, tests, and deployments happen the same way every time. This reduces manual errors, prevents environment drift, and gives teams confidence that changes are safe to release.

          Automate the Repetitive Work (Build, Test, Infra)

          Manual tasks slow teams down and introduce risk. Automation of builds, testing, infrastructure provisioning, and configuration management frees engineers to focus on higher-value work. As the system grows, these automated processes protect delivery speed and maintain consistency across environments.

          Monitor and Improve with Metrics (Lead time, MTTR, etc.)

          Monitoring is only effective if it drives action. Teams should track key metrics like lead time and mean time to recovery (MTTR), and tie alerts directly to accountable owners. Structured incident reviews and continuous feedback loops turn monitoring data into real improvements, reducing repeated failures and improving overall reliability.

          Shift Security Left (DevSecOps as default)

          Security should be part of the pipeline from the start. By integrating automated scans, access controls, and compliance checks early, teams reduce late-stage blockers and prevent vulnerabilities from reaching production. Security becomes a natural part of the workflow rather than an afterthought.

          Make It a Culture and Operating Model (ownership, feedback)

          DevOps succeeds when it is embedded in the team’s culture. Clear service ownership, fast feedback loops, and shared responsibility for incidents create an environment where continuous improvement thrives. Automation and tooling support the model, but the culture and defined processes are what make it sustainable.

          Minimum Deliverables Checklist

          devops best practices

          When implementing DevOps, it’s important to define concrete deliverables to ensure reliability and consistency.

          Key deliverables include:

          • CI/CD Deliverables: A standardized pipeline covering automated builds, testing, staging and production deployments, and rollback procedures.
          • Monitoring and Incident Deliverables: Centralized logging, actionable alerts tied to ownership, and structured incident response processes.
          • Runbook and Change Management Deliverables: Operational runbooks, escalation procedures, release checklists, and post-incident review templates.
          • Security and Access Control Deliverables: Role-based permissions, secrets management, automated vulnerability scanning, and audit logging.

          Together, these deliverables create a clear operational framework that supports faster, safer, and more predictable software delivery.

          What to Outsource vs Keep In-house

          devops best practices

          Deciding what to handle internally versus what to outsource is critical for mid-sized teams with limited DevOps resources. A clear strategy ensures that your team focuses on high-value work while partners handle tasks that benefit most from specialized expertise.

          What You Should Keep In-house

          Core responsibilities that directly affect your product and business outcomes should remain in-house. This includes strategic decisions about architecture, service ownership, and compliance responsibilities. Internal teams should also maintain control over final security decisions and business-critical workflows to ensure accountability and alignment with company goals.

          What You Can Outsource Safely

          Tasks that are repetitive, highly technical, or require specialized expertise can often be outsourced. This includes setting up CI/CD pipelines, implementing infrastructure as code, integrating monitoring systems, and managing automated security tools. By leveraging external partners for these areas, your internal team can focus on product development and operational oversight rather than low-level setup and maintenance.

          Where a Hybrid Model Works Best

          Many mid-sized teams benefit from a hybrid approach, where external partners build and maintain foundational systems while internal teams oversee operations and gradually take ownership. This model allows for knowledge transfer, continuous improvement, and ensures that your team retains control over critical decisions while still leveraging external expertise for speed and scalability.

          Common Failure Patterns and How to Avoid Them

          devops best practices

          Even with the right tools, DevOps initiatives can fail if teams neglect process, ownership, or culture. Understanding common failure patterns helps mid-sized teams avoid costly mistakes and implement DevOps effectively.

          Tool-first Implementation (no operating model)

          Many teams focus on adopting tools before defining how work should flow, which leads to inconsistent practices and confusion. Tools alone cannot enforce collaboration, standardization, or accountability. To avoid this, first establish a clear operating model that defines workflows, responsibilities, and feedback loops, then select tools that support that model.

          No Ownership and Unclear Responsibilities

          When no one is explicitly responsible for a service, incidents, or releases, tasks fall through the cracks and problems persist. Clear ownership at both team and individual levels ensures accountability. Documenting roles and responsibilities, and linking them to incident management and monitoring processes, prevents delays and repeated errors.

          CI/CD Exists but Releases Are Still Manual

          Implementing CI/CD pipelines is not enough if the final deployment still relies on manual steps. This undermines the benefits of automation and introduces human error. Fully automating the release process, including rollback and verification, ensures that teams can deploy reliably at any time.

          Monitoring Without Action (alerts, but no response)

          Setting up monitoring without defining how alerts will be handled creates noise and frustration. Alerts must be actionable, assigned to responsible owners, and tied to follow-up processes. Combining monitoring with structured incident response and post-mortem reviews ensures that data leads to meaningful improvements rather than ignored warnings.

          Cost Drivers and Engagement Models

          devops best practices

          Understanding the costs of implementing DevOps and choosing the right engagement model is essential for mid-sized teams planning their budgets.

          What Drives Cost Up

          The figures below are indicative estimates based on global market data. Actual costs may vary depending on your region, team size, and project scope.

          DevOps costs vary widely depending on project complexity, required expertise, and tool selection. Setting up a CI/CD pipeline typically costs between USD5,000 and USD15,000, while implementing IaC ranges from USD8,000 to USD25,000. Full-stack managed DevOps services usually run USD8,000 to USD20,000 per month, and 24/7 monitoring or incident response adds another USD2,500 to USD6,000 per month. Larger projects, such as full CI/CD automation or cloud migrations, can cost USD100,000 to USD200,000, and enterprise-wide DevOps transformations may exceed USD200,000.

          Common Engagement Models (Fixed, T&M, Dedicated Team)

          There are several common engagement models with different cost implications and flexibility. Fixed-scope projects, such as implementing CI/CD or security integration, usually fall between USD10,000 and USD50,000, offering predictable budgets. Time & Materials (T&M) contracts provide flexibility for evolving requirements but monthly costs vary depending on hours and expertise. Dedicated team arrangements, where external DevOps engineers work alongside internal teams, typically cost USD6,000 to USD14,000 per engineer per month.

          How to Choose a DevOps Partner

          devops best practices

          Choosing the right DevOps partner is about more than just price or reputation. Start by looking for proof of delivery, such as case studies or concrete results like CI/CD pipelines and monitoring systems. It’s also important to make sure they follow strong security and governance practices, including proper access controls, audits, and compliance.

          Equally important is knowledge transfer. Clear documentation and training help your team maintain systems on their own. Finally, consider their operating support. Reliable partners provide ongoing monitoring, incident response, and continuous improvement to keep your systems running smoothly and securely.

          How IVC Can Support

          devops best practices

          ISB Vietnam (IVC) supports mid-sized teams with a structured, practical approach to DevOps implementation.

          Why teams choose IVC

          IVC is especially strong in security-sensitive and high-scale environments. We have experience designing secure systems in domains such as healthcare and logistics, and building low-latency systems that handle large volumes of device or event data. 

          We also emphasize team enablement, including documentation, handover, and cost optimization guidance, so the system remains stable and affordable after launch.

          IVC’s Core DevOps Deliverables

          IVC focuses on a minimum set of deliverables that reduce release risk and operational workload. We implement Infrastructure as Code (Terraform or CloudFormation) to recreate Dev, Test, and Prod environments consistently. 

          We also build automated CI/CD pipelines (for example, GitHub Actions or AWS CodePipeline) with safe release controls, including rollback paths when deployments fail. On the operations side, we set up dashboards and alert rules, and deliver runbooks so teams can handle routine operations and incidents with clear procedures.

          Security is built in through least-privilege IAM, network isolation, and audit-ready access and change logs.

          Operational quality and safeguards

          To keep DevOps reliable after go-live, IVC emphasizes operational controls such as automated rollback design in CI/CD, least-privilege access control, audit-ready logs for access and changes, and runbooks that define how to respond when alerts fire. We also support knowledge transfer so teams can operate confidently without depending on a few key individuals.

          DevOps is not just about tools. It is about building a repeatable operating model that improves delivery speed, strengthens reliability, and reduces operational risk as your systems grow. For many mid-sized teams, the real challenge is knowing where to start, what “good” looks like, and how to balance internal ownership with external expertise.

          With a clear roadmap, defined ownership, and measurable outcomes, DevOps becomes a structured capability instead of an ongoing experiment.

          Ready to move from reactive operations to structured DevOps?

          Let's turn uncertainty into a clear, actionable roadmap grounded in real delivery.
