VMware virtual infrastructure simplifies IT so companies leverage their storage, network, and computing resources to control costs and respond faster. The VMware virtual infrastructure approach to IT management creates virtual services out of the physical IT infrastructure, enabling administrators to allocate these virtual resources quickly to the business units that need them most.
Hardware management is completely separated from software management, and hardware equipment can be treated as a single pool of processing, storage and networking power to be allocated and de-allocated on the fly to various software services.
In a virtual infrastructure, users see resources as if they were dedicated to them while the administrator manages and optimise resources globally across the enterprise.
Why is Virtual Infrastructure Important?
The VMware virtual infrastructure architecture enables businesses to lower IT costs through increased efficiency, flexibility and responsiveness. Managing a virtual infrastructure allows IT to quickly connect and manage resources to business needs.
