Virtualization of x86 architecture servers has been an extremely dynamic market (and a major trend) since VMware introduced its server products in 2001. For several years, competition was very limited. However, since 2006 (with the first commercial versions of Xen) and 2008 (with the release of Microsoft's Hyper-V), very viable alternative choices have emerged. Initially used just for cost reduction, server virtualization is now also being used to speed up operational processes and server deployment, create disaster recovery solutions where they didn't exist before, and improve server availability.
