Gazprom is a large global oil and gas producer with dozens of subsidiaries. A key part of its IT organization, Investgazavtomatika, is upgrading to the Windows Server 2012 operating system and using it as a foundation for building a private cloud environment that all Gazprom subsidiaries can share. By taking advantage of the many high-availability features in Windows Server 2012 and increased virtual machine density, Gazprom can reduce server costs by 25 percent a year and greatly expand its portfolio of services. Gazprom has deployed Microsoft System Center 2012 and plans to use it to centrally manage its newly consolidated cloud infrastructure. System Center 2012 is a complete suite of data center management tools designed specifically for the needs of private cloud environments.
