Spring Cloud Gateway is a gateway that provides routing, security, monitoring, and resiliency capabilities for microservices. It acts as an API gateway and sits in front of microservices, routing requests to the appropriate microservice. The gateway uses predicates and filters to route requests and modify requests and responses. It is lightweight and built on reactive principles to enable it to scale to thousands of routes.

- 3. API Gateways - Then and Now Many API Management Gateways can be dated back to SOA and these tend to have been implemented as centralized servers. But as microservices became more popular, modern lightweight independent and decentralized micro-gateway applications have appeared – such as Spring Cloud Gateway.
