openshift: java ee in the clouds
DESCRIPTION
OpenShift is Red Hat's polyglot Platform as a service which allow you to run a large range of services in the cloud. In this talk I will give an introduction to OpenShift, what it offers and how it works. The talk will be in two parts. First part is about OpenShift in general and how to use it from the command line and the web console Second part is about how JBoss Developer Studio works with OpenShift and how it both coexist and extend the experience you get with "plain" OpenShift. This part will focus especially on how well the JavaEE and mobile parts of Developer Studio works with OpenShift. The talk is intended to be practical and guided by attendees question.TRANSCRIPT
