What does virtualization enable on a server?

Virtualization technology allows multiple virtual machines (VMs), or guests, to coexist on a single physical server while maintaining isolation from one another. This capability is significant because it enables efficient resource utilization. Each virtual machine operates as if it were a separate physical machine, running its own operating system and applications independently.

In service-oriented or cloud environments, this isolation is crucial, as it enhances security and stability. Any issues arising in one VM, such as resource hogging or crashes, will not directly affect the performance or operation of other VMs on the same host.

This feature of virtualization allows organizations to consolidate hardware, reduce costs, and better manage workloads, leading to enhanced scalability and flexibility in deploying applications. Each VM can be tailored to specific requirements while sharing the underlying hardware resources, perfecting the balance between performance and resource utilization within a server environment.
