The “Conference Application”, first presented during Devoxx Belgium in November 2016, is a MicroProfile demo that showcases the integration of different MicroProfile vendor implementations. The demo consists of four microservices, each developed by a different vendor implementation of MicroProfile. This demo application is maintained by the community.
The "Conference Application" mimics an application used by the attendees of a technical conference to:
-
See a list of sessions to attend (Session microservice)
-
See a list of speakers delivering sessions (Speaker microservice)
-
Schedule sessions to attend (Schedule microservice)
-
Vote for a session (Vote microservice)
The application also has a web-app component as a front-end user interface that directly subscribes to each of the microservices.
Here is a pictorial description of the architecture of the "Conference Application":
The following table summarizes each microservice, its underlying open source implementation, and the vendor that developed the microservice business logic.
| Microservice name | Description | Open Source Implementation | Vendor |
|---|---|---|---|
microservice-session |

Thorntail |
Red Hat |
microservice-schedule |
Schedule microservice allows the scheduling of conference sessions |

In Appendix A of this book, you will find the resources to download, build and run an adapted version of the "Conference Application", in which the microservice-session microservice, developed in the Thorntail implementation of MicroProfile, has been enriched with the MicroProfile JWT Propagation, Health Check, Metrics, and Config APIs.
