Over the last few weeks Canadian ActiveState has released version 2.0 of its Stackato and California based CumuLogic has moved out of Beta to a 1.0 release.
Both are private PaaS platforms that enable enterprise developers to deploy, manage, and monitor applications, while meeting the security and privacy requirements.
CumuLogic offers a closed source Java PaaS for running applications in private, public and hybrid cloud environments.
On the counterpart ActiveState Stackato provides an open source platform with paid support.
Both products are competing with Red Hat OpenShift, other versions of CloudFoundry (including VMware), a number of other PaaS solutions, and hand-built solutions on IaaS.
