Jakarta EE Application Health Check With MicroProfile Health

MicroProfile is a community driven initiative, built on top of the Jakarta EE Core Profile.

It is a collection of abstract specs that form a complete solution to developing cloud native, Jakarta EE microservices. The MicroProfile Health API is one of these specs, and is designed to help your applications be able to respond to automated health probes in a cloud native deployment environment.

Developing cloud native enterprise Java applications requires that your application plays nicely with cluster management systems like Kubernetes. The MicroProfile Health API helps achieve that objective.
