🧱 Architecture

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.

🚀 Getting Started

📦 Lightweight RPC API

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.
