API Gateway
Day 10 · Azure · Integration
API Gateway
One front door in front of many services. Azure API Management terminates the call, checks the key, enforces the rate limit, then routes to the right backend.
One hostname, many backendsClients call api.yourco.com. Products and operations map each path to an App Service, Function or container behind the scenes.
Policies replace duplicated codeKeys, JWT validation, quotas and rate limits are declared once as APIM policies — not copy-pasted into every service.
Backends can move freelySwap, split or version a service behind the gateway and the client contract never changes.
