When migrating virtual servers, what is the best minimum CPU resource setting on the second host for an application server with 50% utilization?

When migrating virtual servers, particularly for an application server with a utilization rate of 50%, the goal is to ensure that we allocate sufficient CPU resources to maintain performance while avoiding over-provisioning.

The correct answer indicates that the application server should have a minimum CPU resource setting of 1,600 MHz, which is appropriate when factoring in the application's utilization. Since the server's utilization is at 50%, allocating resources that reflect needed capacity allows for optimal performance without wasting resources.

In practical terms, for an application to function efficiently at 50% utilization, the CPU should ideally be clocked to provide enough overhead to meet peak demands without being excessive. Thus, 1,600 MHz is a balanced figure for accommodating the workload effectively while minimizing resource waste.

The mention of additional web servers in the choice, which are set at 2,300 MHz each, suggests adequate resources for those as well, assuming they are not overutilizing capacity. This allocation maintains a harmony between what is necessary for smooth operations versus what is available.

This understanding of resource allocation is vital in cloud environments, where efficient use of resources can lead to cost savings and improved performance.
