Virtualization technologies optimize server deployment by allowing multiple virtual machines (VMs) to run on a single physical server. This process maximizes hardware utilization, reduces energy costs, and simplifies management. Through hypervisors, virtualization software allocates resources dynamically to VMs based on demand, enabling better workload distribution and scaling. Additionally, virtualization facilitates easier backup, recovery, and testing of applications in isolated environments without impacting the entire system. As a result, organizations can achieve operational efficiency, flexibility, and cost savings in their infrastructure management.
