Because virtualization potentially supports several VMs on a given server, use of the server's computing resources is significantly higher. It's not uncommon to find a virtual server using 50% or more of its computing resources.The cost benefits of virtualization are well understood: There are simply fewer servers, and each virtualized server can perform more business work per dollar spent on hardware, power, cooling, management and maintenance.ptimizing hardware for cost-effective server utilization. Cost-effectiveness often means getting more utilization from server hardware, but this requires insight about each server's hardware, the ways that hardware is utilized by each VM and the underlying operating system hypervisor.
Later, in the 1970s, the emergence of the virtual machine came about. With the virtual machine, an entire system (software and hardware) could be emulated in a contained environment. The virtual machine is perhaps the first form of virtualization, as we know it today.atabase virtualization allows the use of multiple instances of a DBMS, or different DBMS platforms, simultaneously and in a transparent fashion regardless of their physical location. These practices are often employed in data mining and data warehousing systems.
