What is vSphere Hypervisor?
vSphere Hypervisor is a free, bare-metal hypervisor that virtualizes servers, allowing multiple virtual machines (VMs) to run on a single physical server. Developed by VMware, vSphere Hypervisor is a key component of the vSphere suite, which provides a comprehensive platform for virtualization, storage, and networking management. By decoupling the operating system and applications from the physical hardware, vSphere Hypervisor enables greater flexibility, scalability, and reliability in IT infrastructure.
Main Benefits of vSphere Hypervisor
The use of vSphere Hypervisor offers several benefits, including improved resource utilization, reduced hardware costs, and enhanced disaster recovery capabilities. Additionally, vSphere Hypervisor provides a robust and secure environment for virtual machines, with features such as encryption, access control, and auditing.
