Overview of Virtualization

Virtualization Basics and Cloud Computing

An Overview of Virtualization

• Allows you to create multiple simulated environments or dedicated resources from a single, physical hardware system.
• Hypervisor/Host
• Virtual Machine/Guest

Hypervisor

• Separate the physical resources from the virtual environments
• Hypervisors can sit on top of an OS (end user) or be installed directly onto hardware (enterprise).

Virtual Machine

• The virtual machine functions as a single data file.
• The hypervisor relays requests from the VM to the actual hardware, is necessary.
• VMs doesn’t interact directly with the host machine.
• Physical hardware is assigned to VMs.
