In short, a virtual data center is cloud-based IT infrastructure solution that delivers cost-savings and the ability to scale. It combines server virtualization (which allows multiple VMs to run on the same physical machine), network virtualization and storage virtualization. This unified framework delivers IT as an service to applications as well as end-users on premises, the cloud or in a hybrid environment.
A VDC can cut down on time spent by IT teams maintaining physical hardware. This allows them to focus more on productive tasks, such as the deployment and management of business applications. It also lowers operational costs by removing the need for expensive hardware acquisition and management. In addition, it reduces the power bill and energy consumption by keeping servers cooler and more efficiently running.
With a VDC, IT administrators can easily increase capacity to address rapid increases in bandwidth or other IT resource requirements. This is particularly helpful for businesses experiencing seasonal fluctuations in business activity as it allows IT departments to allocate additional resources quickly and economically without the expense of purchasing or installing new hardware.
Additionally by using a VDC, IT administrators can centrally manage and manage their entire IT infrastructure stack via a single, intuitive management tool. This can reduce the cost of administration and allow IT to attain higher levels of productivity and efficiency that can be translated into real business value, such as reduced costs and higher productivity.
