The document summarizes a presentation about OpenShift for Java developers. It includes an agenda that covers what was achieved in the last 12 months with OpenShift, an overview of the OpenShift Java story, and a demonstration of using Eclipse with OpenShift. The presentation defines OpenShift as a platform as a service (PaaS) that allows developers to focus on code instead of configuration and speeds up deployment. It provides details on OpenShift flavors, supported technologies, and improvements made over the last year, including bigger gear sizes and support for environments variables and rollbacks.
