“Shared” in the context of a rented server means that multiple customers share the server’s resources. Server virtualization is a technology that enables multiple instances to run simultaneously on the same physical server. To achieve this, administrators use hypervisors, which serve as a separation layer between the hardware and the virtual servers. The hypervisor abstracts the server software from the underlying hardware. It dynamically distributes resources such as processing power, memory, storage space, and network connections to virtual machines (VMs).
Each virtual machine (VM) runs isolated from the others, so that problems in one VM do not affect the others. Through virtualization, different operating systems and applications can be operated in parallel on a single physical server. This optimizes hardware utilization and reduces the need for physical servers. Server virtualization forms the foundation for modern cloud computing environments, including hybrid cloud solutions. It also improves the flexibility, scalability, and efficiency of IT infrastructure.
