Univention Corporate Server (UCS) is a reliable, pre-configured Linux server operating system free of charge featuring:
- Active Directory-like domain services compatible with Microsoft Active
- A mature and easy-to-use web-based management system for user, rights
and infrastructure management; a scalable underlying concept suited for
single server scenarios as well as to run and manage thousands of clients
and servers for thousands of users within one single UCS domain
- An app center providing single-click installation and integration of many
business applications from 3rd parties and Univention
- Management capabilities to manage Linux- and UNIX-based clients
- Command line, scripting interfaces and APIs for automatization and
- Docker containers can be run on UCS
- Single sign-on with optional two-factor authentication
Thus, UCS is the best fit to provide Microsoft Server-like services on the cloud or on the premises, to run and operate corporate IT environments with Windows- and Linux-based clients and to extend those environments with proven enterprise software, also either on the cloud or on the premises. Since UCS 4.0, UCS also manages OpenStack- and Amazon EC2-based cloud resources.
The complete source code of Univention Corporate Server is provided under an Open Source licence. The software is tried-and-tested and regularly updated. UCS is available free of charge as a Core Edition without functional limitations for commercial and private use. Companies preferring guaranteed, individually adjustable support can subscribe to different UCS maintenance services.
UCS features user, group and rights administration, an integrated IP management (DNS, WINS, DHCP), file and printer services. UCS is ideal for positioning services or applications on the cloud. It allows the simple, secure integration of cloud-based applications with established administration procedures. The included tool Univention AD Takeover allows the simple migration of a Microsoft Active Directory to UCS via the integration of Samba 4. The module Active Directory Connection, in turn, allows the mounting of a UCS domain in an existing AD domain, e.g., for using UCS as a platform for applications from the Univention App Center. This App Center provides, besides further UCS components such as Univention Corporate Client (UCC), which is a centrally managed client operating system, numerous Open Source products from third-party manufacturers, such as the groupware solutions Zarafa and Open-Xchange, the backup solution "SEP sesam", the document management system agorum®core, the customer management solution "SugarCRM" and the dropbox alternative "owncloud". All the software available in the Univention App Center is seamlessly integrated in UCS and can be easily installed and uninstalled with a few mouse clicks and is also available as ready-to-use VM images for KVM, VMware, VMware ESX, and VirtualBox.
