What technology does VMotion rely on for migrating VMs?

VMotion utilizes live migration technology to facilitate the seamless transfer of virtual machines (VMs) from one physical server to another without any downtime. This technology allows running VMs to be moved while they remain operational, providing continuous availability and minimizing service interruptions.

Live migration ensures that all the VM's memory, virtual CPU state, and network connections are moved to the target host dynamically, maintaining the running state of applications and services within the VM. Therefore, organizations can efficiently manage workloads, balance loads across physical resources, and perform hardware maintenance without affecting business operations.

The other technologies mentioned do not serve the same purpose. Backup technology primarily focuses on creating copies of data for recovery, while snapshot technology captures a point-in-time image of a VM for easy rollback. Storage technology, while important for managing where and how data is stored, is not specifically related to the live migration of VMs and doesn't enable the direct migration process that VMotion implements.
