AppScale

AppScale is an open-source hybrid cloud platform. AppScale implements a number of popular APIs including those of Google App Engine, MapReduce (via Hadoop), MPI and others. AppScale executes as a guest virtual machine (guestVM) over any virtualization layer that can host an Ubuntu Lucid image. We currently test and support the Xen hypervisor and the Kernel Virtual Machine (KVM). AppScale also automatically deploys over the Amazon EC2 public cloud and Eucalyptus private clouds. AppScale has been developed and is maintained by the RACELab at UC Santa Barbara. AppScale executes applications written in the Python, Java, and Go programming languages.

The latest stable release is AppScale 1.5, released July 28th, 2011.
