Virtualization is a technology that creates abstract versions of physical resources traditionally bound to physical hardware. Resources can include desktop environments, servers, operating systems, storage, and networks. Virtualized environments are simple to manage and are a cost-effective way for small and medium-sized businesses to expand their IT infrastructure.
Infrastructure as a Service (IaaS) is a cloud-based service that delivers processing power, storage, and network infrastructure to businesses on an as-needed basis. It is a scalable alternative to a traditional data center that allows businesses to avoid the cost of provisioning and maintaining their own physical IT infrastructure.
