What is vSphere Hypervisor?
vSphere Hypervisor is a free, enterprise-class hypervisor for deploying and managing virtual machines (VMs) on a physical host server. Developed by VMware, it is designed to provide a stable, efficient, and scalable virtualization platform for a wide range of use cases. With vSphere Hypervisor, users can create and manage virtual machines, allocate resources, and monitor performance in a centralized manner.
Main Features of vSphere Hypervisor
vSphere Hypervisor offers a range of features that make it an ideal choice for virtualization and container workflows, including:
- Support for multiple virtual machine formats, including VMX, VMDK, and OVF
- High-performance networking and storage capabilities
- Advanced security features, such as role-based access control and VM encryption
- Integrated monitoring and troubleshooting tools
