🧱 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:
