Orleans is a cross-platform software framework for building scalable and robust distributed interactive applications based on the .NET Framework[2][3] or on the more recent .NET.
Orleans was originally created by the eXtreme Computing Group at Microsoft Research[2] 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.[4]
Starting with cloud services for the Halo franchise, the framework has been used by a number of cloud services at Microsoft[5] and other companies since 2011.[6] The core Orleans technology was transferred to 343 Industries and is available as open source since January 2015.[7] The source code is licensed under MIT License and hosted on GitHub.[8]
Orleans runs on Microsoft Windows, Linux, and macOS and is compatible with .NET Standard 2.0 and above.[9]
Some Orleans features include:[10]
The Electronic Arts BioWare division created Project Orbit. It is a Java implementation of virtual actors that was heavily inspired by the Orleans project.[13][14]
