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 began as a research project at the "University of California, Santa Barbara Computer Science Department under the supervision of Professor Chandra Krintz. 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. 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. In September 2014, AppScale Systems won a Bossie Award from "InfoWorld for best open source data center and cloud software
