AppScale is the world’s most popular open source PaaS. AppScale implements Google App Engine in Open Source, meaning you have the same benefits of the brilliant App Engine development model without being locked-in to Google. You now have the flexibility to run your GAE application on any public or private cloud, including on-premise. AppScale provides “freedom for your application.” You still retain the agile App Engine model to quickly develop and launch your application, but now you have the freedom to choose which public cloud to use. Easy. Fast. AppScale.
