== Spring Cloud Alibaba Dubbo
|
||
|
||
=== Introduction
|
||
|
||
Dubbo Spring Cloud is based on Dubbo Spring Boot 2.7.3[1] and Spring Cloud 2.x development, whether the developer is a Dubbo user or a Spring Cloud user.
|
||
Easily navigate and move apps up at a cost close to “zero” costs. Dubbo Spring Cloud is designed to simplify Cloud Native development costs, improve R&D performance, and improve application performance.
|
||
|
||
=== Features
|
||
|
||
Since Dubbo Spring Cloud is built on top of the native Spring Cloud, its service governance capabilities are considered Spring Cloud Plus.
|
||
Not only does it fully cover the Spring Cloud native features [5], but it also provides a more stable and mature implementation, as shown in the following table:
|
||
|
||

| Distributed configuration | Git、Zookeeper、Consul、JDBC | Spring Cloud Distributed Configuration + Dubbo Configuration Center[6]
|
||
| Service registration and discovery | Eureka、Zookeeper、Consul | Spring Cloud Native Registration Center[7] + Dubbo Native Registration Center[8]
|
||
| Load balancing | Ribbon（Random, RoundRobin） | Dubbo built-in implementation (random, polling, etc. + weights, etc.)
|
||
| Circuit Breakers | Spring Cloud Hystrix | Spring Cloud Hystrix + Alibaba Sentinel[9] etc.
|
||
| Service-to-service calls | Open Feign、`RestTemplate` | Spring Cloud service call + Dubbo `@Reference`.
