Apache Dubbo Project
Apache Dubbo is an easy-to-use Web and RPC framework that provides multiple language implementations(Java, Go, Rust, Node.js, Web) for communication, service discovery, traffic management, observability, security, tools, and best practices for building enterprise-ready microservices.
We are now collecting Dubbo user info to help us to improve Dubbo further. Kindly support us by providing your usage information on Wanted: who's using dubbo, thanks :)
Architecture
- Consumer and provider communicate with each other using RPC protocol like triple, tcp, rest, etc.
- Consumers automatically trace provider instances registered in registries(Zookeeper, Nacos) and distribute traffic among them by following traffic strategies.
- Rich features for monitoring and managing the cluster with dynamic configuration, metrics, tracing, security, and visualized console.
Getting started
Follow the instructions below to learn how to:
Programming with lightweight RPC API
Dubbo supports building RPC services with only a few lines of code while depending only on a lightweight SDK (<10MB). The protocol on the wire can be Triple(fully gRPC compatible and HTTP-friendly), Dubbo2(TCP), REST, or any protocol of your choice.
Building a microservice application with Spring Boot
It's highly recommended to start your microservice application with the Spring Boot Starter dubbo-spring-boot-starter provided by Dubbo. With only a single dependency and yaml file, and optionally a bunch of other useful spring boot starters, you can enable all of the Dubo features like service discovery, observability, tracing, etc.
Next, learn how to deploy, monitor, and manage the traffic of your Dubbo application and cluster.
