Controlling Virtual Machine Sprawl
Nov 1, 2012
Virtualization not only improves hardware efficiency via server consolidation, itdramatically reduces the time required to bring a new server online from weeks or months to hours or minutes. This ability to bring machines online quickly provides companies with improved business agility. As with most improvements new issues can be created, and if not addressed, can reduce a virtual infrastructure’s overall efficiency over time. Virtual machine sprawl is one of the biggest concerns facing many companies using desktop or server virtualization. The ability to quickly create virtual machines without the disciplines and controls of the physical world results in machines being provisioned unnecessarily without proper justification and approval, over-provisioned (too much CPU, memory, or disk), or consuming resources well after they no longer are required.
