0. The service container is responsible for starting, loading, and running the service provider.
1. Upon launch, the service provider registers its services with the registry.
2. When the service consumer starts, it subscribes to the registration center for the services it needs.
3. The registry returns the service provider address list to the consumer, and if there is a change, the registry will push the change data to the consumer based on a long connection.

Then choose another call.
5. Service consumers and providers, the cumulative number of calls in memory and call time, timed to send statistics every minute to the monitoring center.
