Armeria – go-to microservice framework

Armeria is a microservice framework for any situation.

You can build any type of microservice leveraging your favorite technologies, including gRPC, Thrift, Kotlin, Retrofit, Reactive Streams, Spring Boot and Dropwizard.

This is free and open source software.

Features include:

  • HTTP/2:
    • Supports HTTP/2 on both TLS and cleartext connections.
    • Supports protocol upgrade via both HTTP/2 connection preface and traditional HTTP/1 upgrade request.
    • Fully compatible with existing HTTP/1 servers.
    • Integrated PROXY protocol support for interoperability with load balancers such as HAProxy and AWS ELB.
  • Capable of running services using different protocols, all on a single port. No need for any proxies or sidecars. Enjoy the reduced complexity and points of failure, even when migrating between protocols.
  • Building microservices:
    • Metrics.
    • Circuit breaker.
    • Client-side health-check and load-balancing.
    • Service discovery from various sources such as DNS and ZooKeeper.
    • Distributed call tracing via Zipkin.
  • Headache-free RPC with documentation service – documentation service allows you to browse the complete list of services and their documentation from a web browser. You can also make a real RPC call in human friendly JSON format and share the URL of the call with your colleague.
  • Reusable components – provides various reusable components called ‘decorators’ in a clean, consistent, flexible and user-friendly API. You can also write a custom decorator if ours doesn’t work for your use case.
  • Integrate seamlessly with your favorite frameworks and languages.
  • Flexible service discovery and client-side load-balancing – provides various service discovery mechanisms, from Kubernetes-style DNS records to ZooKeeper data nodes. Send periodic or long-polling pings to exclude unhealthy endpoints autonomously. Choose the best load-balancing strategy for you — weighted round-robin, sticky-session, etc. You can even write a custom service discovery or load-balancing strategy.
  • Interactive web-based debug console.
  • Compatibility with existing Java EE web applications.
