Azure API Management Gateway

The Azure API Management gateway (data plane) acts as a facade to backend services, routing API requests, enforcing policies, verifying credentials, applying rate limits and quotas, caching responses, and emitting telemetry. It supports managed cloud-hosted and self-hosted containerized deployments for hybrid and multicloud environments.

  title: Azure API Management Gateway
  description: The Azure API Management gateway acts as a reverse proxy between API consumers and backend services. It routes
    requests, applies policies (authentication, rate limiting, caching, transformation), and emits telemetry. The gateway
    proxies calls to APIs configured in the management plane.
