Building on Java EE Success the Cloud Native Java

PUTTING ENTERPRIS E JAVA IN THE CLOU D

Getting the full picture from the Jakarta EE Community

Over 1,800 developers participated in the Eclipse Foundation survey in March 2018 to answer questions on Java and Jakarta EE. One thing remains perfectly clear: Java still reigns supreme. Now, a large community of open source developers are pooling their efforts to accelerate the rate of innovation for Java EE’s next incarnation — as the cloud native Jakarta EE platform.

It’s a polyglot world... What programming languages are you using at work?

Building on Java EE succe ss Sometimes it’s easy to take for granted a technology that most enterprise IT organizations rely on to run their most critical applications.

The most challenging How can the Eclipse Foundation aspects of working evolve Jakarta EE to meet your with Java EE cloud needs?

Missing technologies Faster pace 20% and specifications 47% of innovation

Large memory 40% requirements Native integration 57% with Kubernetes

Slow startup Better support

The cloud native Java imperative

Organizations are becoming more comfortable deploying mission critical Java applications beyond the data center.

How many developers run their Java applications in NOW the cloud? WITHIN 2 YEARS
