gRPC + Nacos

• In Nacos, microservices typically communicate over HTTP. However, with the introduction of Nacos 2.0, the platform has adopted gRPC for heartbeat signals
• Consider transitioning your services to gRPC to benefit from reduced latency, particularly in the serialization and deserialization processes

Service Producer

• Extend or implement your RPC service in the ProtoBuf file
• Register the service name, IP address, and gRPC port with Nacos

Service Consumer

• Subscribe to Nacos' InstanceChangedEvent to filter for instance information of the gRPC service providers
• Maintain a map of <ServiceName, CycleList>, updating it in response to each InstanceChangedEvent received
• Business code could easily obtain a usable ManagedChannel, create a stub, and initiate gRPC requests
