It’s time to talk about the API gateway.

In a modern infrastructure — especially in a microservices environment — you probably know what I’m referring to. But it’s worth being explicit about it:

“An API gateway takes all API calls from clients, then routes them to the appropriate microservice with request routing, composition, and protocol translation. Typically it handles a request by invoking multiple microservices and aggregating the results, to determine the best path.”
