Intent

Aggregate calls to microservices in a single location: the API Gateway. The user makes a single call to the API Gateway, and the API Gateway then calls each relevant microservice.

Applicability

Use the API Gateway pattern when

• you're also using the Microservices pattern and need a single point of aggregation for your microservice calls
