Question
Q.3. Explain the benefits of virtualization.
Answer
Virtualization benefits include improved hardware utilization through consolidation, isolation between workloads, easier provisioning/migration of virtual machines, and reduced hardware/energy costs.
The benefits of virtualization include: improved hardware utilization, since multiple virtual machines can share the resources of a single physical server (server consolidation), reducing the number of underutilized physical machines needed; workload isolation, since each virtual machine operates in its own isolated environment, so a fault or security compromise in one VM does not directly affect others sharing the same physical host; flexibility and ease of provisioning, since new virtual machines can be created, cloned, resized, or migrated between physical hosts quickly, without needing to procure and configure new physical hardware; and reduced capital and operating costs, since server consolidation lowers the total hardware, power, cooling, and data-center space requirements for a given computing workload, directly reducing both capital expenditure and ongoing energy costs.
