What are the advantages of utilizing Distributed Resource Scheduler (DRS)?

The advantages of utilizing Distributed Resource Scheduler (DRS) primarily revolve around its capacity to balance workloads and optimize resource allocation across a cluster of virtual machines. DRS intelligently manages resources by continuously monitoring the current resource usage of virtual machines and the underlying hosts within a cluster. When it detects imbalances—such as when one host is heavily loaded while another is underutilized—it can automatically migrate virtual machines using vMotion to balance the resource usage. This ensures that all virtual machines run efficiently and that performance is maximized by allocating resources where they are needed most.

While DRS does enhance the overall performance and efficiency of resource management in a virtualized environment, it does not involve encryption of data, provide direct VM access to storage, or create physical redundancies for VMs, which are functions associated with different technologies or features. For instance, data encryption during transfer is typically handled by different security protocols, while direct VM access to storage relates more to storage configurations rather than resource management, and physical redundancies pertain to high availability strategies rather than resource distribution.
