AppScale is a free and open-source software framework for running Google App Engine applications. The primary goal of AppScale is to allow developers to have application portability. It is a cloud computing platform (marketed as platform as a service), supporting Xen, Kernel-based Virtual Machine (KVM), Google Compute Engine, Amazon EC2, RackSpace, OpenStack, CloudStack, and Eucalyptus. It is developed and maintained by AppScale Systems, based in Santa Barbara, California. AppScale was initially funded by Google, IBM, the NSF, and NIH.
AppScale supports the ability to host multiple App Engine applications with the ability to swap out distributed datastores such as Accumulo, HBase, Hypertable, and Apache Cassandra. It has support for Python, Go, PHP, and Java applications by implementing scalable services such as the datastore, memcache, blobstore, users API, and channel API.
