'''Quattor''' is a generic open-source tool-kit used to install, configure, and manage computers. Quattor was originally developed in the framework of European Data Grid project (2001-2004). Since its first release in 2003, Quattor has been maintained and extended by a volunteer community of users and developers, primarily from the community of grid system administrators.
The Quattor tool-kit, like other configuration management systems, reduces the staff required to maintain a cluster and facilitates reliable change management. However, three unique features make it particularly attractive for managing [[Grid computing|grid]] resources:

* Federated Management: The open, modular nature of the tool-kit permits system administrators at different institutes to share the management of their distributed resources.
* Shared Configuration and Management Efficiency: Quattor encourages the re-use of configuration information in such a way that it can be distributed and used with little or no modification at different sites, facilitating the distribution of best practices without the need for each site to implement configuration changes.
* Coherent Site Model: Quattor allows an administrator to develop a site model that, once constructed, can be used to manage a range of different resources, such as real machines, virtual machines and cloud resources.

These features are also attractive beyond the grid context. This has been confirmed by the growing adoption of Quattor, by both large commercial organisations <ref>Wall Street and Technology, http://www.wallstreetandtech.com/it-infrastructure/216402934</ref> and academic institutions, most of them using the tool-kit to manage consistently their grid and non-grid systems.
