What is VMware ESXi?
VMware ESXi Server is a virtualization software, that means that the VMware ESXi Server is a single physical server who can run multiple virtual machines simultaneously. Each of these virtual machines believes it is running on its own dedicated hardware, and they have the impression that they are separate from the rest of virtual machines, but they are actually on the same hardware which is controlled by VMware ESXi Server. This is an enterprise level virtualization tool which utilizes services that manage numerous virtual machines with greater reliability and efficiency than VMware’s more basic Server product.
The reason for this is because ESXi Server runs on „bare-metal.“ This essentially means that you install the ESXi Server software directly into the computer, without an operating system for it to run on top of.
