Scalable Virtual Machine Multiplexing
Source: University of California
A Virtual Machine (VM) is a software abstraction of a real, physical machine. Virtualization has been around for almost 50 years, beginning with IBM's pioneering work in the 1960s. However, recent years have seen a significant surge in the interest and use of virtualization, driven by better hardware support, increasing power costs and low resource utilizations. Server consolidation is by far the most common application for virtualization - by aggregating multiple services on a single physical machine, organizations can reduce costs and increase the utilization of their infrastructure.
