What is the purpose of enabling vSphere DRS in a virtual machine cluster?

Enabling vSphere Distributed Resource Scheduler (DRS) in a virtual machine cluster primarily serves the purpose of enabling automated VM migration to balance resource usage across the cluster. When DRS is active, it continuously monitors the resource utilization of virtual machines and their host servers. If it detects that a particular host is becoming overutilized while another is underutilized, DRS can automatically initiate the migration of virtual machines from one host to another. This process, known as load balancing, ensures that all resources are used efficiently and helps prevent performance degradation for the workloads running in the virtual environment.

By leveraging DRS, organizations can optimize resource allocation dynamically without requiring manual intervention. This automation not only improves performance but also enhances overall cluster efficiency and resource management.
