Umbraco is an open source content management system (CMS) platform for publishing content on the World Wide Web and intranets. It is written in C# and deployed on Microsoft based infrastructure. The open source backend is released under an MIT License while the UI is released under the Umbraco license[2].
Umbraco was developed by Niels Hartvig in 2000 and released as open source software in 2004[3]. In 2009, CMS Wire described it as one of the leading .NET-based open source CMS systems[4][5]. In 2010, with 1000 downloads a day[6], Umbraco was in the Top 5 most popular downloads via the Microsoft Web Platform Installer, two places below its main rival DotNetNuke[7] and was the 12th most downloaded application from Codeplex, six places below DotNetNuke and 13 places higher than mojoPortal[8].

[edit] Technology
Umbraco is primarily written in C#, stores data in a number of relational databases (commonly Microsoft SQL Server) and works on Microsoft IIS.
[edit] Database tier
In 2008, developer Ruben Verborgh introduced a data abstraction layer, making it possible for Umbraco to support databases other than SQL Server. In version 4 of Umbraco, support for MySQL, SQL Server and VistaDB come as standard[9].
[edit] Deployment
The standard release of Umbraco is typically deployed on IIS in an environment which supports Full Trust. While a Full Trust environment is mandatory to install and operate the standard release, the codebase has been branched and modified to produce a version of the framework and backend UI which supports Medium Trust[10][self-published source?].
Research has also been undertaken on running an Umbraco website on Mono on Linux[11][12].
Umbraco can be deployed on a single physical server running the database and web tier, and this deployment model can be appropriate for small low-cost sites. Umbraco sites which serve content under higher load can also be deployed on a load balanced cluster. Load balanced Umbraco installations can use software or hardware load balancers, and load balanced network files can be shared using a SAN, NAS or a cluster file system or using a file replication service between nodes in the cluster[13][self-published source?].
[edit] Releases
Version 4.1 Beta II was released on 16 February 2010 which refactors a number of key components of the framework[6], including the UI tree control to improve performance and the user experience and parts of the data access layer to reduce the number of database calls.
Version 5 (codenamed "Jupiter") is a rewrite of the framework, built using ASP.NET MVC[14], published in January 2012.
[edit] Design philosophy
Umbraco is built upon Microsoft's .NET Framework, Microsoft SQL Server, and XSLT, a XML-based language used for the transformation of XML documents. It is designed to be a toolkit for building custom software; it integrates existing technologies rather than introduce new ones. For example, Umbraco supports ASP.NET "master pages" and XSLT rather than introducing its own templating language.
[edit] Community
The Umbraco corporation employs a staff of eleven and is supported by a core development team of 15[6] volunteers who work on the open source core platform. Umbraco's community site, "Our Umbraco", has more than 55.000 registered users and developers[citation needed]. Since 2005 there has been an annual developer conference which have taken place in Copenhagen, except in 2007 when it was held in London. In 2009 there were 170[citation needed] attendees and the conference is planned to take place in Copenhagen in June 2010.
[edit] Reception
In August 2009, Umbraco was included in a list of 10 CMS systems recommended by the Danish Version2 magazine. Among these were three systems initially developed in Denmark: Sitecore, TYPO3, and Umbraco.[15]
