ActiveState Stackato and CumuLogic are private PaaS. Over the last few weeks Stackato has moved to a 2.0 version and CumuLogic has moved out of Beta to a 1.0 release. CumuLogic 1.0 is a Java-only PaaS with support for Amazon, HP Cloud Services, and private clouds including Citrix CloudStack, Eucalyptus, OpenStack and VMware vSphere. Stackato has a similar range of public and privae IaaS on which it operates (vSphere, KVM, XenServer, OpenStack, EC2 AMI, HP CS) but it has a much broader set of language compatibilities including .NET.ther new features in Version 2.0 are a centralized web-based management console and some support for charge-back (i.e. billing) through API. Performace management is through integration with New Relic. There is additional security support in multi-tenancy by using Linux Containers (LXC).
