When building serverless APIs with AWS Lambda and API Gateway, we face a critical architectural decision: "Where should we handle JWT (JSON Web Token) validation?" This choice might seem straightforward, but it directly impacts your project's security posture, performance characteristics, maintainability, and AWS costs. Making the wrong decision can lead to a complete system refactoring down the..

When deploying React SPAs (Single Page Applications), many developers consider S3 static hosting as their go-to solution. However, using S3 alone presents several challenges that can impact security, performance, and user experience.

Have you ever wondered how to manage this sensitive data properly?"Well, let me just hardcode it in the source code..." "I'll just write it in a configuration file..." "Setting it as an environment variable should be safe enough, right?"Wait! This is like wri..

As microservice architectures become mainstream, secure inter-service communication is no longer optional—it's essential. This becomes especially critical when one service needs to create and manage users in another service, requiring an authentication system that satisfies both security and scalability requirements.Today, I'll introduce a practical pattern for implementing service-to-service (S..

When building serverless applications, you'll often face the challenge: "How can I assign different permissions to different users in a secure and scalable way?" This becomes especially critical for services like B2B SaaS platforms or e-commerce systems where user roles are clearly defined.Today, I'll show you how to implement a group-based permission management authentication system using Amazo..

When developing serverless applications, you often encounter situations where "additional processing is needed only under specific conditions." For example, sending notifications only when a user's score is low, or executing additional review processes only for requests that don't meet certain thresholds.Today, I'll introduce the EventBridge-Lambda conditional processing pattern that's useful in..
