What is the primary benefit of using VMware's Fault Tolerance feature?

The primary benefit of using VMware's Fault Tolerance feature is continuous availability during a failure. This feature enables a virtual machine (VM) to run simultaneously on two different physical hosts, maintaining an active and a secondary instance. In the event of a failure of the primary host, the secondary instance provides immediate failover, ensuring that workloads remain operational without interruption. This capability is crucial for organizations that require high availability for critical applications, as it minimizes downtime and maintains business continuity.

While other features or enhancements may improve aspects like performance or security in various VMware offerings, Fault Tolerance specifically addresses the need for sustained service availability, which is its defining purpose. Therefore, anyone relying on critical applications would significantly benefit from implementing this feature to avoid service interruptions.
