API Gateway Basics

Front APIs with a gateway

An API gateway centralizes routing, authentication, rate limits, caching, and logging for backend services, simplifying clients and adding consistent policies and observability.

Route and centralize

Front services with consistent domains and paths; handle versioning rules.

Secure access

Apply authentication, JWT validation, and IP safelists where needed.

Protect and optimize

Add rate limits, request size limits, and optional caching for heavy endpoints.

Observe and alert

Emit standardized logs/metrics and tie to dashboards and alerts.
