Virtualization provides the foundation for servers on demand by implementing an on-line operating system that is required for all other operating systems to run on the Cloud. Virtualization also enables the Cloud to rapidly create server space based on end-user demand by simply running a new instance of an operating system on an existing server. Virtualization through the Cloud creates a model by which servers become services and the underlying operation system is no longer a factor in how quickly or easily a new server can be provisioned. Looking at the rapid growth of smart phones you see devices where the applications are not tied to the browser but instead are tied to the underlying operating system. Netbooks will run a phone operating system or Windows® and virtualization is the key to managing all these mobile devices practically. This would indicate in the future that there will be more operating systems not less, but they will allow the end-user to do more, increasing efficiency, productivity, and cost effectiveness via a virtual desktop. All in need of management.
As organizations look to further GreenIT initiatives, another advantage of virtualization in the cloud is the fact that a virtual server can be running Microsoft®, Linux®, or another operating system on the same physical hardware enabling low utilization servers to be paired with high utilization servers allowing significant savings in energy costs.
Another benefit to virtualization in the Cloud is the ability to constantly rebalance servers as their usage spikes and drops and to do quick disaster recovery by moving images from one data center to another and quickly restoring the images on new hardware when current hardware fails.
The Cloud is designed to support IT customers with a simple, flexible and scalable value proposition. Virtualization provides additional benefits that allow IT organizations to truly leverage the level of optimization that Cloud computing promises.
