What is Virtualization?

• Pretty old but to critical to understand
• A system pretends to be two or more
• Simulation of hardware devices or features using software
• Used to create virtual version of something (like network)

Virtualization is the process of using software to create virtual versions of physical hardware, like computers, servers, or networks, allowing multiple systems to run on one machine efficiently.

How Virtualization

Achieved through the use of virtualization software called Hypervisor Hypervisor creates virtualized versions of physical resources Hypervisor allocates these resources to virtual machines (VMs) VM operates as if it were a physical machine Run different applications, operating systems, and services using VMs
