What is Virtualization ?
Virtualization is the process of creating a software-based (or virtual) representation of something rather than a physical one. Virtualization can apply to applications, servers, storage, and networks and is the single most effective way to reduce IT expenses while boosting efficiency and agility for all size businesses.
It’s Not Cloud Computing !!
Cloud computing is not the same thing as virtualization; rather, it’s something you can do using virtualization. Cloud computing describes the delivery of shared computing resources (software and/or data) on demand through the Internet. Whether or not you are in the cloud, you can start by virtualizing your servers and then move to cloud computing for even more agility and increased self-service.
Virtualization Implementation :
Most servers operate at less than 15 percent of capacity, leading to server sprawl and complexity. Server virtualization addresses these inefficiencies by allowing multiple operating systems to run on a single physical server as virtual machines, each with access to the underlying server’s computing resources.
The next step is to aggregate a server cluster into a single consolidated resource – which improves overall efficiency and reduces cost. Server virtualization also enables faster workload deployment, increased application performance, and higher availability.
