In this whitepaper, we will discuss how API Gateway is beneficial as it uses a middleware that helps to reduce the complexity of starting multiple servers and avoid writing scripts.
API gateway is like a passage between an API and its various backend services which takes care of the incoming requests and passes it to the appropriate service for further processing. The results coming from that service are then sent back to the API gateway in the form of a response.
The gateway handles request rate limiting, data usage, request source validation, and access/user authentication, so it accomplishes your goals. Requests are typically processed by invoking multiple microservices and aggregating the results to determine the best path. It can convert between web protocols and non-web-friendly protocols used internally.
An API gateway is a conductor that orchestrates requests handled by your microservices architecture to provide a simplified experience for your users. A translator reduces the number of round trips between the client and the application by converting many client requests into one. An API gateway is set up in front of your microservices and is the entry point for each new request made by your app. This simplifies both client implementations and microservice apps.
