Virtualization technology is a revolutionary concept transforming how organizations utilize their hardware resources and manage IT infrastructure. By way of hypervisors, it allows multiple virtual machines (VMs) using various operating systems (OSs) to run on a single physical server or host.
Virtualization provides a more efficient and cost-effective solution than clustering physical servers, each with its own configurations and maintenance requirements. Instead, you can simplify things and manage all your VMs from a centralized management console.
By abstracting the underlying hardware, virtualization enables virtual environments to be isolated and run independently. This means operating systems, such as Windows or Linux, can coexist on the same physical server without interfering with one another. Each virtual machine functions separately with dedicated resources and an independent software stack.
