VMware ESXi™ is the industry-leading, purpose-built bare-metal hypervisor. ESXi does not rely on a general purpose OS as it installs directly onto your physical server enabling it to be partitioned into multiple logical servers referred to as virtual machines.

vSphere ESXi Hypervisor Features

Improved Reliability and Security

The ESXi bare-metal hypervisor’s management functionality is built into the VMkernel, reducing the footprint to 150 MB. This gives it a very small attack surface for malware and over-the-network threats, improving reliability and security.

Streamlined Deployment and Configuration

With few configuration options and simple deployment and configuration, the ESXi architecture makes it easy to maintain a consistent virtual infrastructure.

Reduced Management Overhead

vSphere ESXi uses an agentless approach to hardware monitoring and system management with an API-based partner integration model. Management tasks are on remote command lines with the vSphere Command Line Interface (vCLI) and Power CLI, which uses Windows

PowerShell cmdlets and scripts for automated management.

Simplified Hypervisor Patching and Updating

Fewer patches mean smaller maintenance windows and fewer scheduled maintenance windows.
