VMware ESXi

VMware ESXi is an “empty” hypervisor included in the VMware vSphere package. Unlike other software applications that require a basic operating system, ESXi is installed directly on a physical server, turning it into a powerful virtual machine host.

Advantages of VMware ESXi

  • Reducing overhead costs. The absence of a basic OS reduces the overhead of resources, providing higher VM performance.
  • Increased security. Features such as Secure Boot ensure that only signed code will work in the hypervisor.
  • Centralized management. With vCenter Server, you can manage multiple ESXi hosts from a single panel.
  • Advanced features. vMotion, High Availability and Fault Tolerance increase the reliability and uptime of virtual machines.

VMware ESXi compared to other hypervisors
