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, Dr. Chris Bunch, 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 Krintz, 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. In late 2017, AppScale Systems started offering commercial support for Eucalyptus private cloud software after DXC Technology chose to stop the development and support of Eucalyptus. This prompted AppScale, led by members of the Eucalyptus founding team, to fork the code and continue developing the software, which was renamed AppScale ATS. ===Open source components=== Datastore API: Apache Cassandra and Apache ZooKeeper Memcache API: memcached Task Queue API: RabbitMQ and Celery XMPP API: ejabberd Channel API: ejabberd Blobstore API: Apache Cassandra and Apache ZooKeeper Images API: Python Imaging Library (PIL) Cron API: Crontab HAProxy: HAProxy ===Supported platforms=== Amazon EC2 CloudStack DigitalOcean Eucalyptus Google Compute Engine Kernel-based Virtual Machine (KVM) Microsoft Azure OpenStack RackSpace SoftLayer (IBM) Xen ===Supported languages=== Go Java PHP Python ==See also== Amazon Web Services Cloud computing Oracle Cloud Platform as a service Serverless computing
