Sentinel is a flow control and reliability library for microservices, providing rate limiting, traffic shaping, concurrency limiting, circuit breaking, and adaptive overload protection. It offers real-time monitoring, framework integrations (Spring Cloud, Dubbo, gRPC, Quarkus), and polyglot support for Java, Go, C++, and Rust.
Use cases
- rate limit burst traffic to protect my microservice
- add circuit breaking for unreliable downstream services
- limit concurrent requests in a Java service
- monitor real-time traffic metrics of my services
- apply adaptive overload protection in a distributed system
- integrate flow control with Spring Cloud or Dubbo
When to choose
- you need battle-tested flow control and circuit breaking for JVM or Go microservices
- you want out-of-the-box adapters for Spring Cloud, Dubbo, or gRPC
- you need real-time monitoring and cluster flow control in cloud-native systems
When to avoid
- you need a standalone API gateway or edge proxy rather than an in-process library
- your stack uses languages without a Sentinel port
- you only need simple client-side HTTP retries without traffic governance
