Api-gateway

An API Gateway acts as a single entry point for client requests in microservices architectures. It enhances performance, enforces security, simplifies routing, supports caching, monitoring, versioning, and more for scalable software systems.

While API Gateways add some overhead and complexity, the benefits generally outweigh the drawbacks—especially for applications built with microservices, multi-versioned APIs, or needing centralized control.

In modern software architecture—especially with the rise of microservices—efficient request routing and system scalability are critical. Two key components that help manage this are the API Gateway and the Load Balancer.
