Which one is better to use, Dubbo or Spring Cloud?

Dubbo and Spring Cloud are two different distributed service frameworks, and the choice of which one to use depends on your specific needs and background. Dubbo is an open-source RPC (remote procedure call) framework developed by Alibaba, focusing on high performance and stability, suitable for microservices architecture in large-scale distributed systems. Dubbo provides features such as load balancing, fault tolerance, and clustering support, making it suitable for scenarios requiring high performance and low latency. If your application needs to handle a large number of concurrent requests and requires high performance and stability, then choosing Dubbo may be more appropriate. Spring Cloud is a set of microservice frameworks developed by the Spring team, built on top of Spring Boot, providing a series of tools and components to simplify the development and deployment of distributed systems. Spring Cloud emphasizes the convenience and flexibility of development, providing features such as service registration and discovery, configuration management, and load balancing, suitable for quickly building and iteratively developing distributed systems. If you are already familiar with the Spring ecosystem and your application requires high development convenience and flexibility, then choosing Spring Cloud may be more appropriate. In summary, if you value high performance and stability and have a high demand for concurrent processing capabilities, choosing Dubbo is more appropriate; if you have a high demand for development convenience and flexibility and are already familiar with the Spring ecosystem, then choosing Spring Cloud is more appropriate. Of course, this does not mean you can only choose one framework, in practice, you can also choose to use a combination according to specific requirements.
