What is the main purpose of the vSphere vMotion feature?

The main purpose of the vSphere vMotion feature is to migrate running virtual machines (VMs) between physical hosts with zero downtime. This capability is crucial for maintaining high availability and minimizing service interruptions during maintenance, load balancing, or hardware upgrades.

vMotion facilitates the live migration of VMs, ensuring that users experience no disruption, which is vital in environments where uptime is critical. The technology works by transferring the active memory and system state of the VM over the network to the destination host, allowing the VM to continue executing while the migration occurs.

This feature is essential for efficiently managing resources, optimizing performance, and conducting planned maintenance without affecting service availability, making it a key tool in any vSphere environment.
