## What it is
Spring Cloud Gateway is an API gateway built on Spring Framework, Spring Boot, and Project Reactor. It provides routing, filtering, and traffic management for microservices architectures.

## Use cases
- route requests to backend microservices
- set up an API gateway for a Spring Boot microservices stack
- add rate limiting and request filtering at the edge
- implement cross-cutting concerns like auth and retries in one place
- load balance traffic across service instances

## When to choose
- you have a Spring Boot or Spring Cloud microservices ecosystem
- you want a reactive, programmable gateway in Java
- you need deep integration with Spring Cloud service discovery and config

## When to avoid
- you need a high-performance non-JVM gateway like Envoy or NGINX
- your stack is not JVM-based
- you only need simple static reverse proxying without custom logic

## Facets
- artifact type: framework
- maturity: stable
- function: api-gateway, routing, proxy, middleware, http-server, rate-limiting
- domain: microservices, apis, backend, web-development
- platform: jvm, cross-platform
- tags: api-gateway, spring-boot, reactive, reverse-proxy, load-balancing, devops, spring
