'''Orleans''' is a cross-platform [[Software framework|software framework]] for building scalable and robust distributed interactive applications based on the .NET Framework<ref name="thenewstack">[https://thenewstack.io/microsofts-orleans-distributed-app-framework-is-now-cross-platform/ Microsoft's Orleans Distributed App Framework Is Now Cross Platform - The New Stack]</ref><ref>[http://hpc-asia.com/open-source-cloud-framework-microsoft/ Open-Source Cloud Framework By Microsoft - HPC ASIA]</ref> or on the more recent .NET.

==Overview==
Orleans was originally created by the ''eXtreme Computing Group'' at [[Organization:Microsoft Research|Microsoft Research]]<ref name="thenewstack" /> and introduced the ''Virtual Actor Model'' as a new approach to building distributed systems for [[Cloud computing|the cloud]]. Orleans scales from a single on-premises server to [[High availability|highly-available]] and globally distributed applications in the cloud.<ref>[https://www.computerworld.com/article/2859286/microsoft-to-release-project-orleans-as-open-source.html Microsoft to release Project Orleans as open source | Computerworld]</ref>

Starting with cloud services for the Halo franchise, the framework has been used by a number of cloud services at Microsoft<ref>[https://www.youtube.com/watch?v=KhgYlvGLv9c Orleans at Microsoft | .NET Conf 2020]</ref> and other companies since 2011.<ref>[https://www.zdnet.com/article/microsoft-opens-early-adopter-program-for-its-orleans-cloud-framework/ Microsoft opens early adopter program for its 'Orleans' cloud framework | ZDNet]</ref> The core Orleans technology was transferred to [[Company:343 Industries|343 Industries]] and is available as [[Open source|open source]] since January 2015.<ref>[https://siliconangle.com/2014/12/17/microsoft-to-make-halo-4-gaming-cloud-engine-project-orleans-open-source/ Microsoft to make Halo 4 gaming cloud engine Project Orleans open source - SiliconANGLE]</ref> The source code is licensed under [[Software:MIT License|MIT License]] and hosted on [[GitHub]].<ref>{{Cite web|url=https://github.com/dotnet/orleans/blob/master/LICENSE|title = Dotnet/Orleans|website = [[GitHub]]|date = 17 February 2022}}</ref>
