An ENTERPRISE MANAGEMENT ASSOCIATES® (EMA™) White Paper Prepared for BMC Software, April 2008
Some forms of virtualization in the IT environment have been in use for decades. However, in recent years, the number and type of virtualization technologies have greatly expanded and entered the mainstream. Virtualization in the IT environment can be applied to servers, storage, networks, applications, and other IT assets. Fundamentally, virtualization hides the physical characteristics of IT infrastructure resources from the way in which other systems, applications, or end users interact with those resources.
Virtualization produces many benefits for business and IT, including cost reduction, improved ROI, increased agility and responsiveness, reduced downtime, and even faster software development cycles. However, virtualization also creates some new challenges. Discovery, monitoring, problem resolution, change management, and other IT management processes are all impacted by virtualization. These processes and their supporting tools must be adapted to properly understand and control virtualized environments.
