19:00 - Lightweight Microservices with Microprofile and Raspberry PIs

Microservices has been buzzword in the last years in software engineering. It helps to solve issues we had with monolith applications, however it also brings new challenges.

Eclipse MicroProfile provides a time to market set of specifications and tools addressing these many challenges. Jean-Louis will be looking on how to use these spec implementations in practice throughout this presentation and show step-by-step examples on how to add monitoring with MP Health and with MP Metrics, security with MP JWT, custom configuration with MP Config, and also teach how to easily provide documentation with MP OpenAPI and much more.

Lightweight will be achieved by deploying and running Docker on raspberry PIs.

20:30 - Stateless Microservice Security via JWT, TomEE and MicroProfile

Microservices based architecture seems to be the common convergence point in the industry. But when it comes to security we are still struggling to evolve from monolithic systems or people oriented architecture. This presentation will be focusing on this landscape and explain how to leverage the quickly evolving MicroProfile JWT specification to secure Microservices and in a fully stateless and scalable manner. We’ll introduce the specification in a quick and no nonsense fashion and move on to several code examples that show how to setup JWT verification and obtain trusted claims via lookup or dependency injection. For our playground, we’ll be using Apache TomEE, fully open source lightweight Java EE server and MicroProfile implementation.
