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 host. Developed by VMware, vSphere Hypervisor is a key component of the vSphere suite, providing a robust and reliable platform for virtualization and containerization. With its immutable storage, rollbacks, and cluster repositories, vSphere Hypervisor offers a cleaner, safer, and more efficient way to manage virtual infrastructure.
Main Benefits
By using vSphere Hypervisor, organizations can enjoy several benefits, including improved resource utilization, increased flexibility, and enhanced disaster recovery capabilities. Additionally, vSphere Hypervisor provides a cost-effective solution for virtualization, as it is free to download and use.
