🧱 Architecture

• Communication between consumers and providers is done via RPC protocols like Triple, TCP, REST, etc.
• Consumers dynamically discover provider instances from registries (e.g., Zookeeper, Nacos) and manage traffic using defined strategies.
• Built-in support for dynamic config, metrics, tracing, security, and a visualized console.

Start quickly with our 5-minute guide

Dubbo allows you to build RPC services using a minimal codebase and a lightweight SDK. It supports protocols like:

• Triple (gRPC-compatible)
• Dubbo2 (TCP)
• REST
• Custom protocols

🌱 Microservices with Spring Boot

Kickstart your project using Spring Boot Starter.

Using just a dependency and a YAML config, you can unlock the full power of Dubbo: service discovery, observability, tracing, etc.
