Dubbo is a Java RPC framework and microservices governance platform designed for high-performance remote procedure calls in distributed architectures. It provides the foundational components necessary to connect distributed services across a network, including a binary data serialization library and a distributed service registry.
The platform distinguishes itself through a comprehensive governance suite that manages service discovery, load balancing, and traffic routing. It enables precise control over network traffic via conditional routing and a pluggable extension mechanism based on a service provider interface.
The framework covers a broad range of capabilities, including distributed request tracing for observability, TLS transport encryption and request authentication for security, and centralized metadata management. It also supports integration with Spring Boot and utilizes interface definition languages to synchronize service contracts between providers and consumers.
