Historically, J2EE servers were huge monolithic beasts. While the second generation of the platform, called Java EE, improved a lot, there are already production-ready solutions to bring even more flexibility to run enterprise Java applications. Many major vendors, including IBM, Red Hat and Payara, strive to provide lightweight and extensible runtimes to power microservices, cloud deployments and reactive architectures already. Their individual efforts are naturally followed by an open collaboration within the MicroProfile.io initiative. I invite you to join the adventure with me and follow the quest for a new generation enterprise Java platform. We will explore what has happened in the world of enterprise Java recently, including the progress of the Java EE 8 specifications and the features already provided by some interesting open-source projects. Afterwards, we will have a closer look at the MicroProfile.io initiative and how its future direction can be formed even with your contribution. Lots of coding and demonstrations using Payara Micro included to illustrate the concepts.
