Project Overview
This API Gateway service acts as a central entry point for all client requests to various microservices in a distributed application architecture. It handles cross-cutting concerns such as authentication, authorization, rate limiting, request routing, and monitoring. Built with Node.js and Express, it features a plugin architecture for extensibility and uses Redis for caching and rate limiting implementations.
Features
- API request routing and load balancing
- Authentication and authorization
- Rate limiting and throttling
- Request/response transformation
- Caching implementation
- Logging and monitoring
- Service discovery integration
Challenges
Designing a system that could handle high traffic volumes while maintaining low latency was challenging. Additionally, implementing effective rate limiting that didn't impact legitimate users required careful consideration.
Solution
I implemented a distributed rate limiting system using Redis and designed an efficient caching strategy to reduce backend load. The service was containerized with Docker for easy scaling and deployed with orchestration tools.
