What does the term "vMotion" imply in VMware?

The term "vMotion" in VMware specifically refers to the technology that enables the live migration of running virtual machines (VMs) from one physical host to another without any downtime. This means that users can continue to access the applications running on the VM uninterrupted while the underlying hardware may change. vMotion is crucial for maintaining service availability, performing load balancing, and executing maintenance on hosts without affecting the running workloads.

This capability is particularly important in environments where uptime and availability are critical. The seamless transfer of a VM during vMotion occurs while the VM is still running, utilizing shared storage and a high-speed network connection, thus ensuring that there is no noticeable impact on performance from the user's perspective.

In contrast, the other options do not define the functionality of vMotion. For example, taking backups or creating snapshots involves creating copies of VMs or their states for recovery purposes, which is different from the live migration process. Increasing virtual machine disk space pertains to storage management and does not relate to the VM's operational continuity during host changes.
