VMware is a virtualization and cloud computing software provider based in Palo Alto, California. With VMware server virtualization, a hypervisor is installed on the physical server to allow for multiple virtual machines (VMs) to run on the same physical server. VMware allows web hosting companies to reduce cost through the integration of virtual hosts on the server. You can conveniently add the virtual servers without having to spend money to buy additional hardware. In case you want to upgrade your hardware, you can easily do so by resetting the operating system’s requirement to the new hardware requirements.
