What is vSphere Hypervisor?
The vSphere Hypervisor, formerly known as ESXi, is a popular Type-1 hypervisor developed by VMware. It is a bare-metal hypervisor, which means it is installed directly onto the host machine’s hardware, providing a layer of abstraction between the physical hardware and the guest virtual machines (VMs). This hypervisor is widely used in data centers, cloud computing environments, and virtualized infrastructures.
