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.

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.

Learn the key differences between horizontal and vertical scaling in distributed systems. Discover how each approach impacts system performance, cost, and growth capacity.

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.

When designing scalable systems, one of the most critical decisions you'll face is how to distribute traffic across your servers. Two core models are widely used, stateless and stateful load balancing.
