Hosted by the Eclipse Foundation, Jakarta EE is the home of open source, cloud native Java innovation. Working together, the world’s Java ecosystem leaders, including Fujitsu, IBM, Microsoft, Oracle, Red Hat, SAP, and Tomitribe, are advancing Java EE and Jakarta EE to support moving mission-critical applications and workloads to the cloud. This presentation provides an overview of the various cloud native Java initiatives within the Eclipse community.
