How Service Discovery Solves the Problem

The Service Discovery pattern addresses the above challenges by introducing a central registry and lookup mechanism. Here’s how it solves the problems:

• Dynamic Registration: Each service instance, when it starts, registers its address (host/port) with a central Service Registry. It also de-registers when shutting down. This way, the registry always has a current listing of active service instances. Clients no longer need hard-coded addresses – they can query the registry to get the latest location of a service.
