What is "appscale"

AppScale is an open-source cloud computing platform that automatically deploys and scales unmodified Google App Engine applications over public and private cloud systems, as well as on-premises clusters. AppScale is modeled on the App Engine APIs and has support for Go, Java, PHP, and Python applications.

The goal of AppScale is to provide developers with a rapid, API-driven development platform that can run applications on any cloud infrastructure. AppScale decouples app logic from its service ecosystem to give developers and cloud administrators control over app deployment, data storage, resource use, backup and migration.

AppScale is developed and maintained by AppScale Systems, Inc., based in Santa Barbara, California, and Google.
