You will learn how to externalize and inject both static and dynamic configuration properties for microservices using MicroProfile Config.

You will learn to aggregate multiple configuration sources, assign prioritization values to these sources, merge configuration values, and create custom configuration sources.

The application that you will be working with is an inventory service which stores the information about various JVMs running on different hosts. Whenever a request is made to the inventory service to retrieve the JVM system properties of a particular host, the inventory service will communicate with the system service on that host to get these system properties. You will add configuration properties to simulate if a service is down for maintenance.
