## What it is
A Spring Cloud auto-configuration library that adds rate limiting to Spring Cloud Netflix Zuul API gateways via Zuul filters. It supports multiple rate limit policies (per user, origin, URL, or global) and pluggable storage backends such as Redis, Consul, JDBC, Bucket4j, and Hazelcast.

## Use cases
- rate limit requests through a Zuul API gateway
- prevent DoS attacks on microservices endpoints
- return 429 when a client exceeds its request quota
- throttle per authenticated user or request origin
- share rate limit state across gateway instances with Redis or Consul

## When to choose
- you run Spring Cloud Netflix Zuul as your API gateway and need built-in rate limiting
- you need flexible per-service rate limit policies with distributed storage backends

## When to avoid
- you use Spring Cloud Gateway or another gateway instead of Netflix Zuul
- you need a general-purpose rate limiter outside a Zuul filter chain

## Facets
