In a microservice architecture, the API Gateway pattern plays an important role, providing several benefits. It prevents clients from knowing anything about how the application is broken up into microservices or needing to know where those microservices can be accessed. It can optimize interactions with the backend services, by reducing the number of requests required to complete a task. It can act as the front line of security, ensuring that only authorized clients are able to access services. It can address service level requirements such as rate-limiting. And those are just a few benefits of an API gateway.
In this session, we’ll look at how to add an API gateway to you microservice architecture with Spring Cloud Gateway. Spring Cloud Gateway is a fully-featured implementation of API gateway that supports a variety of protocols in addition to HTTP and is fundamentally reactive. You’ll see how standing up a gateway in front of several backend services can simplify a client, optimize request, and more.
