Orleans (software framework)

Orleans is a cross-platform software framework for building scalable and robust distributed interactive applications based on the .NET Framework.
Overview.
Orleans was originally created by the "eXtreme Computing Group" at Microsoft Research and introduced the "Virtual Actor Model" as a new approach to building distributed systems for the cloud. Orleans scales from a single on-premises server to highly-available and globally distributed applications in the cloud.
Starting with cloud services for the Halo franchise, the framework has been used by a number of cloud services at Microsoft and other companies since 2011. The core Orleans technology was transferred to 343 Industries and is available as open source since January 2015. The source code is licensed under MIT License and hosted on GitHub.
Orleans runs on Microsoft Windows, Linux, and macOS and is compatible with .NET Standard 2.0 and above.
