Dubbo |ˈdʌbəʊ| offers six key functionalities, which include transparent interface based RPC, intelligent load balancing, automatic service registration and discovery, high extensibility, runtime traffic routing, and visualized service governance.
Transparent interface based RPC
Dubbo provides high performance interface based RPC, which is transparent to users.
Intelligent load balancing
Dubbo supports multiple load balancing strategies out of the box, which perceives downstream service status to reduce overall latency and improve system throughput.
Automatic service registration and discovery
Dubbo supports multiple service registries, which can detect service online/offline instantly.
Dubbo’s micro-kernel and plugin design ensures that it can easily be extended by third party implementation across core features like Protocol, Transport, and Serialization.
Runtime traffic routing
Dubbo can be configured at runtime so that traffic can be routed according to different rules, which makes it easy to support features like blue-green deployment, data center aware routing, etc.
Visualized service governance
Dubbo provides rich tools for service governance and maintenance such as querying service metadata, health status and statistics.
