In this chapter, we learned about the MicroProfile Health Check and JWT Propagation projects. You should now understand what a health check is and how to add application-specific checks, known as procedures. These allow your microservice to describe its non-trivial health requirements in a cloud environment. You should also understand how JWTs can be used to provide an authentication and authorization capability on top of your microservices to control access to your endpoints. You should also understand how content from the JWT can be used to augment your microservice in user-specific ways.
The next chapter will introduce the MicroProfile Metrics and OpenTracing features. These allow your microservices to provide additional information regarding common and application metrics and to trace the interactions between microservices.
