Server Virtualization is a technology that allows multiple virtual servers to run on a single physical server. This is achieved by using a software layer called a hypervisor, which divides the physical resources, such as CPU, memory, and storage, among the virtual servers. Each virtual server operates independently, enabling efficient resource utilization and reducing hardware costs. By consolidating servers, Server Virtualization simplifies management and improves scalability. Organizations can quickly deploy new virtual servers as needed, making it easier to respond to changing demands. Additionally, it enhances disaster recovery options, as virtual servers can be easily backed up and restored.
