AppScale is an "open-source "serverless computing platform that automatically deploys and scales unmodified "Google App Engine applications over public and private clouds, 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.
The platform allows developers to focus on the business logic of building scalable applications, freeing them from the need to concentrate on deployment and scaling logic. 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 includes high-level APIs for persistence, asynchronous execution, distributed memory cache, user authentication, and more. It handles service discovery, load-balancing, fault-tolerance, and auto-scaling. It also allows IT operations and cloud administrators to provide a consistent, tunable environment for running and maintaining apps on multiple cloud infrastructures. AppScale is developed and maintained by AppScale Systems, Inc., based in "Santa Barbara, California, and Google.
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 2017, Dimitrii Calzago joined AppScale as CTO from Hewlett Packard Enterprise, where he was Director of Cloud R&D.
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. AppScale partnered with Optimal Dynamics on April 11, 2016. AppScale was part of the AliLaunch Program, August 9 2016. Chandra Kritz, Chief Science Officer of AppScale, was featured on Dev Radio in the episode titled "How to Rescue your apps with the help of AppScale" on December 16, 2016.
