If you are aware of a microservices architecture, then there we have several spring boot applications (microservices) running on different ports or routes. An API gateway acts as a single point of entry for a collection of microservices. In simple words, all microservices can be accessed through a single port or route. It is a non-blocking and reactive gateway that provides several features like routing, filtering, load balancing, circuit breaking, and more. In this article first, we’ll look at the spring cloud gateway architecture and then implement it.
