What does service registration and discovery mean? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Service registration and discovery means that the service process registers its own location in the registry, and the client application process initiates a query to the registry to obtain the location of the service. An important role of service discovery is to provide a list of available services.

The role of service registration and discovery

Service registration: the service process registers its own location with the registry. It usually registers its own host and port number, and sometimes authentication information, protocol, version number, and details of the running environment.

Service discovery: the client application process initiates a query to the registry to get the location of the service. An important role of service discovery is to provide a list of available services

Service registration, service registry, service discovery

The relationship among the three is that the information of starting the service is uploaded to the service registry through the service registration mechanism, and the service discovery mechanism obtains the information of the available services in real time through the service registry.

The ways of service registration include self-registration and third-party registration. Self-registration means that when the service starts, the service automatically uploads the information to the service registry and synchronizes it through the heartbeat. Third-party registration means that the information about starting the service is uploaded to the service registry through a third-party service and updated through a certain mechanism. The disadvantage is to ensure the high availability of third-party services.

The service registry is also a service cluster that maintains a database in which information about available services is stored.

Service discovery means that when you need to use a service, the client can connect to the server by reading the service registry to get the available service information. The ways of service discovery include client-side service discovery and server-side service discovery.
