🧱 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.

🌱 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.
