We laugh at people who tell us Java is slow. The dark days of EJB2 are over. This tutorial shows you how to develop enterprise applications with just a few lines of code that can even run on a Raspberry Pi. MicroProfile optimizes Enterprise Java for a microservices architecture and delivers application portability across multiple runtimes. You can use a subset of Jakarta EE to develop MicroProfile applications, using JAX-RS, CDI, and JSON-P, and extend it with Config, JWT, Fault Tolerance, Health Check, Metrics, OpeanAPI, and OpenTracing. With live-coding examples, this presentation shows you how to get hands-on with MicroProfile and rediscover the pleasure of developing enterprise applications.
