AppScale GTS is a cloud application platform designed to provide an independent implementation of Google App Engine APIs. It allows applications developed for the App Engine programming model to run on infrastructure outside Google’s hosted environment, including privately managed systems and supported cloud infrastructure.
The platform was designed around an application execution environment and a collection of services corresponding to the APIs provided by Google App Engine. These services handle application execution, data storage, background processing, and other operations needed by hosted applications. Developers can use familiar App Engine interfaces while infrastructure administrators manage the underlying computing and storage resources.
AppScale GTS includes components responsible for application lifecycle management, service configuration, data storage, and communication between applications. Its architecture supports deployments across multiple machines, with separate components providing application routing, administrative services, and persistence.
The project’s historical source code remains publicly available under the Apache License 2.0. Development and commercial support for the GTS platform have ceased, but the source remains available for examination, modification, and reuse under its licence.
This is free and open source software.
