VMware ESXi
VMware ESXi is a bare-metal hypervisor that is part of the VMware vSphere suite. Unlike other software applications that require an underlying operating system to run, ESXi is installed directly on the physical server, turning it into a powerful virtual machine host.
Benefits of VMware ESXi
- Reduced overhead. The absence of a base OS reduces resource overhead, providing higher VM performance.
- Enhanced security. Features such as Secure Boot ensure that only signed code will run in the hypervisor.
- Centralized management. with vCenter Server, you can manage multiple ESXi hosts from a single dashboard.
- Advanced capabilities. VMotion, High Availability and Fault Tolerance increase reliability and uptime of virtual machines.
