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.[3] AppScale is modeled on the App Engine APIs and has support for Go, Java, PHP, and Python applications.[4]

The goal of AppScale is to provide developers with a rapid, API-driven development platform that can run applications on any cloud infrastructure.[5] 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.[6]

AppScale is developed and maintained by AppScale Systems, Inc., based in Santa Barbara, California, and Google.[7]


AppScale began as a research project at the University of California, Santa Barbara Computer Science Department under the supervision of Professor Chandra Krintz.[8] The project was originally funded by the NSF, with additional funding from Google, IBM and NIH. In 2012, co-founders Dr. Chandra Krintz, Chief Scientist, Dr. Navraj Chohan, Development Lead, and Woody Rollins, CEO founded AppScale Systems to commercialize the private PaaS AppScale technology. Rollins, a pioneer in private cloud infrastructure, was a co-founder and former CEO of Eucalyptus Systems.[9] In 2014, Graziano Obertelli joined AppScale as VP of Operations from Eucalyptus Systems, where he was a co-founder.

In April 2014, AppScale Systems was named a 2014 Cool Vendor in PaaS by Gartner, Inc.[10] In September 2014, AppScale Systems won a Bossie Award from InfoWorld for best open source data center and cloud software[11]
