Virtualization Complete Notes


What is Virtualization:

Virtualization is the abstraction of computer resources; the creation of a logical representation of things such as servers, storage and network resources, rather than the actual things themselves. Server consolidation is the most common application of virtualization technology. Other capabilities include storage consolidation, network consolidation and desktop virtualization; a client/server approach by which multiple users maintain individualized desktops on a single server.

We are turning to online solutions more and more because of the convenience and flexibility they provide. This is why virtualization has become such a popular technology option for Canadian organizations in many industries.
