Virtual Desktop Infrastructure (VDI)
Previously, it made a lot of sense to dedicate a separate physical server to each specific application. By isolating applications on dedicated hardware, you could limit their exposure to potential security threats – and when security failures did happen, you could limit them to a single machine. By dedicating a physical computer and its operating system to a single application, IT departments maintain greater protection against attackers, who have to find another way in. Virtualization platforms have made it far easier and much faster to create and deploy servers and applications than was possible when physical limitations governed system rollouts.

What is Virtualization? Virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system (OS), a server, a storage device or network resource. Source - http://en.wikipedia.org/wiki/Virtualization
Industry Comments ESG Research indicates that security professionals lack virtualization knowledge and best practice models for server virtualization security. Gartner survey: “ 40% of virtualization deployment projects were undertaken without involving the information security team in the initial architecture and planning stages.” Gartner analyst Neil MacDonald wrote: “Virtualization is not inherently insecure. However, most virtualized workloads are being deployed insecurely.“
What is Cloud Computing? Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
