In the cloud environment, it is essential to allow services to report, and eventually publish, the overall health status to a defined endpoint. This can be achieved through MicroProfile Health Check, which allows a service to report the overall status as "UP" if it is available and "DOWN" if it is unavailable. This information can be collected by a service orchestrator, which can then use the health reports to make decisions.

<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-smallrye-health</artifactId>
</dependency>
Once the preceding library is available, we can add an implementation...
