2. What is Virtualization?
The Foundation of Modern IT Infrastructure
Abstracting the Physical
Virtualization creates virtual versions of physical computing resources like servers, operating systems,
storage, and networks. It acts as an abstraction layer over hardware, allowing multiple independent
Virtual Machines (VMs) to run on a single physical machine.
This fundamental technology enables:
Virtualization is the cornerstone of cloud computing and modern data centers, optimizing costs,
simplifying resource management, and accelerating service delivery by decoupling software from
hardware.
Efficient hardware utilization
✓
Enhanced flexibility and deployment speed
✓
Improved scalability to meet demands
