"Virtualization Definition

"Let's begin with a quick introduction of virtualization to set the stage for the following exploration. Virtualization is nothing more than an abstraction over physical resources to make them shareable by a number of physical users (see Figure 1).

"From this definition, we could categorize many things as virtualization that have historically not been so (such as early time sharing systems). But this is the essence of virtualization, and as we'll find, creates many interesting and unique technologies.

"Virtualization and Cloud Computing

"Cloud computing is another technology creating large amount of press these days. It's interesting to note that virtualization is the key enabler of cloud computing and cloud infrastructures in general (both public and Private Cloud computing).

"Virtualization enables dynamically provisionable infrastructure (servers, storage, networking bandwidth, etc.) while also making it much simpler to manage. Without virtualization, resources would be more difficult to provision and share, making them less cost effective."
