The Kolektor Group is a European manufacturer of electric motor parts. The Slovenian firm has enjoyed rapid growth through acquisition, but this has meant new IT services and more servers. To curb server expansion, Kolektor first turned to VMware virtualization software. However, when licensing costs soared and VMware management tools disappointed, Kolektor jettisoned VMware and switched to Windows Server 2008 R2 Datacenter with Hyper-V technology. Kolektor calculates that it will save U.S.$1.5 million in software licensing, hardware, and energy savings over the next few years. By using Hyper-V and Microsoft System Center data center solutions, Kolektor has been able to grow the business by a factor of ten without IT staff increases. The IT staff can deliver new services in minutes rather than hours, has sped up application performance by 30 percent, and has increased server reliability.
