The process of microservice engine CSE registration discovery is described as follows:
1. When the microservice starts, it will register the instance information to CSE, including the basic information of the instance, such as application name, microservice name, instance address, etc.
2. When the microservice needs to call the business data of other microservices, it will query the instance information from the configuration center and cache the local information into the instance. The cache will be updated through mechanisms such as event notification and real-time query
3. Realize point-to-point calls between microservices through real-time cached address information. When there are multiple instances of microservices, different access strategies can be configured
