Why Spring Cloud Alibaba Isn’t the Villain: A Critical Look at Dubbo, Nacos, and Sentinel

Point 1: Remote Call RPC

The quoted article claims Spring Cloud must use Feign and Ribbon for remote calls and load balancing, suggesting that replacing them with Dubbo makes the system "unrecognizable".

The author counters that Spring Cloud Alibaba’s Dubbo integration is compatible with the Feign programming model; see the example repository at https://github.com/spring-cloud-incubator/spring-cloud-alibaba/tree/master/spring-cloud-alibaba-examples/spring-cloud-alibaba-dubbo-examples.

Feign and Ribbon are not part of Spring Cloud’s core; the actual standard load‑balancer is spring-cloud-loadbalancer, now part of Spring Cloud Common. Its repository is https://github.com/spring-cloud-incubator/spring-cloud-loadbalancer.

Point 2: Service Registry

The quoted article states that Spring Cloud’s default registry is Eureka, while the author’s version uses Nacos and suggests alternatives like Zookeeper, Consul, or Etcd.

The author explains that after Eureka’s deprecation there is no single optimal choice; teams should select a registry that fits their stack and cost considerations. Nacos is already independently released, and Spring Cloud Alibaba merely provides a starter for Spring Cloud users.

Point 3: Circuit Breaker and Rate Limiting

The quoted article claims Hystrix is the default circuit‑breaker, now deprecated, with resilience4j as the recommended replacement, and criticizes Sentinel for lacking registry integration.

The author notes that while building a custom circuit‑breaker is possible, open‑source projects like Sentinel offer valuable features and can be beneficial to the industry, even if they require adaptation for specific architectures.

Conclusion

The author observes a trend of technical self‑media prioritizing clicks over accuracy, leading to exaggerated or misleading statements about technologies. He encourages readers to verify claims themselves, maintain independent thinking, and understand the underlying concepts of Spring Cloud Alibaba rather than accepting sensationalized opinions.
