10 Most Common Use Cases of an API Gateway
API7.ai’s blog post “10 Most Common Use Cases of an API Gateway” explains how API gateways have become essential in managing modern microservice architectures. Acting as a single, secure “front door” for all client requests, a gateway simplifies routing, strengthens security, and improves scalability and developer efficiency. The article outlines ten core functions: centralized routing; authentication and authorization; rate limiting; response caching; full observability via logging and tracing; request and response transformation; version management; TLS/SSL termination; protocol translation (e.g., REST to gRPC); and data aggregation for front-end efficiency. By consolidating these cross-cutting concerns, gateways reduce code duplication and improve performance, resilience, and compliance
