What type of resource management does vMotion facilitate?

vMotion facilitates the real-time migration of virtual machines without downtime, which is a critical feature in VMware environments. This technology allows the seamless transfer of a running virtual machine from one physical host to another within a cluster while maintaining continuous service availability. By utilizing vMotion, organizations can perform maintenance on physical servers or balance workloads across resources without interrupting the end user's experience.

This capability is particularly useful in scenarios where a physical host may require maintenance, enabling administrators to move virtual machines to other hosts to ensure optimal performance and resource utilization. Moreover, vMotion helps in load balancing by allowing migrations to distribute workloads evenly across physical resources based on demand in real time.

Other options, such as database management or configuration management, do not align with the primary function of vMotion. Similarly, while physical server allocation is related to resource management, it does not specifically pertain to the live migration capabilities that vMotion provides.
