A free PaaS, OpenShift helps developers build, test, deploy, and manage applications in a cloud. OpenShift incorporates Git and Jenkins, provides Apache and JBoss servers, and supports languages such as Node.js, Ruby, Python, PHP, Perl, and Java. Unlike other open source projects in this space, OpenShift managed to produce a general availability release. Cloud Foundry may eventually pull ahead with the addition of support from IBM, but this was OpenShift's year in the sun.
