So, What is Dubbo?

Dubbo [ ] is a service framework enpowers 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.
• RPC: 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.
