So, What is Dubbo?
Dubbo [
] is a distributed service framework empowers applications with service import/export capability with high performance RPC.
It's composed of three kernel parts:
- Remoting: a network communication framework provides sync-over-async and request-response messaging.
- Clustering: a remote procedure call abstraction with load-balancing/failover/clustering capabilities.
- Registry: a service directory framework for service registration and service event publish/subscription
Dubbo can:
- Integrate different types of RPC solutions(RMI/Hessian...) with unified behavior by the abstraction layer of RPC
- Support out-of-box, plug-able load balancing and fault tolerance strategies.
- Achieve graceful service upgrade/downgrade with service registry.
