Virtualization is one aspect of cloud solutions that is critically important to their success and particularly the ability for a cloud solution to be cost effective. Without virtualization most cloud solutions would fail because they could not provide a cost advantage.
Virtualization typically means the process of abstracting the functions, services and interface of a particular system whether it be hardware, software or a hybrid. Once abstracted, these functions and services can be scaled up and down and sub-divided to provide multiple instances of the service within a single system. That lets a virtualization vendor offer systems that can dynamically scale to meet demand and that can also be shared. The net result is a system that is more efficient and cost-effective. CompareBusinessProducts has research and articles that can help you figure out the right virtualization solution for your needs.
