Abstract: Virtualization or cloud computing is the buzzword today. Virtual machines have been in use for many years, and some would say we have come full circle. The fundamental concept of a VM revolves around a software application that behaves as if it were its own computer. This chapter discusses how virtualization happens. It provides an understanding of the various methods of virtualization, hypervisors, and highlights the main categories of virtualization. The categories are full virtualization, paravirtualization, hardware-assisted virtualization, operating system virtualization, application virtualization, network virtualization, storage virtualization, and service virtualization. There are many benefits to virtualization. With power becoming more expensive and a trend towards going green, virtualization offers cost benefits by decreasing the number of physical machines required within an environment. There are additional benefits that virtualization offers such as more effective disaster recovery and better resource management. Also, the cost and complexity of disaster recovery and business continuity management are greatly reduced by using virtualization technology. An investigator must understand these concepts in order to properly assess the environment.
