Service Governance in Microservice Architecture: Registration, Load Balancing, Rate Limiting, Circuit Breaking, Configuration Center, and Monitoring

Today the article introduces service governance in microservice architecture, starting with a brief comparison between monolithic and microservice structures, explaining how SpringBoot/Jar deployment works and how microservices split into multiple services using Nacos and Dubbo.

It then details the first governance aspect—service registration and discovery via Nacos.

The next topic is load balancing, where Dubbo’s algorithms select appropriate service instances among multiple deployments.

Following that, the article covers rate limiting and circuit breaking. It explains how traffic throttling protects the system from overload and how circuit breaking isolates failures, both handled by Sentinel in the Spring Cloud Alibaba stack.

The next section discusses the configuration center, showing how Nacos enables dynamic loading of core configuration without rebuilding and redeploying the application.

Finally, the article describes service monitoring, including server CPU, memory, disk, network, JVM GC, QPS, latency, and distributed tracing. It notes that Prometheus handles resource and metric collection while SkyWalking provides call‑chain tracing.
