Solution

Add a new component – a service discovery service – to the system landscape, which keeps track of currently available microservices and the IP addresses of its instances.

Solution requirements

Some solution requirements are as follows:

Automatically register/unregister microservices and their instances as they come and go.

The client must be able to make a request to a logical endpoint for the microservice. The request will be routed to one of the available microservice instances.

Requests to a microservice must be load-balanced over the available instances.

We must be able to detect instances that currently are unhealthy, so that requests will not be routed to them.
