Jakarta EE - the New Open Source Life of Java EE

We are living in a new era of information technology. All people like me, who started work at the beginning of the 2000s, have gone through a constant but gradual evolution of languages, frameworks, and architectures. The last year has marked a great change in the way we approach a software release.

The great competition that drives the global market has changed the cultural approach of companies, which now have a milestone target—the reduction of time to market. The need to release a new business service as soon as possible is the main target of a company, regardless of their business area.

From an information technology point of view, this need has been translated into a complete review of development platforms and their updating and evolution processes.

From an enterprise point of view, this change, defined as digital disruption, is leading to the need to review company structures with regard to the organization of roles and skills, as well as to the policies of continuously updating to keep up with market needs. The community side of developers has led to a conceptualization of ideas as has not been seen for some time.

The best way to comprehend all the ideas that are being born around these concepts is through the open source model.

In this chapter, we will cover the following topics:

• Open source
• The Java programming language
• OpenJDK 9 and 10
• Java EE – MicroProfile.io – Jakarta EE
