[13] Virtualization

This creates virtual versions of physical PC components: OS, Storage, Network

This hypervisor runs directly on hardware.

• TYPE 1: BARE METAL

• TYPE 2: HOSTED

This hypervisor runs on top of existing OS

• TYPE 1: BARE METAL

• TYPE 2: HOSTED

This manages virtual resources (CPU's, memory, network interface)

What does it mean when a hypervisor creates an abstraction between a virtual machine (VM) and hardware?

• It allows VMs to directly access the hardware without interference.

• It creates a layer that manages and distributes hardware resources for VMs.

• It restricts all VMs to share the same operating system.

• It disables the ability to run multiple VMs on one machine.

Answer explanation

the hypervisor acts like a translator and organizer, making sure each VM gets its fair share of resources and doesn’t step on another VM's toes

This creates virtual versions of physical hardware components. They run OS on the same machine w/o direct hardware access

• Hardware Virtualization

• Operating System Visualization

• Network Virtualization

• Storage Virtualization

This virtualizes the operating system to run multiple instances. Furthermore, multiple apps share the same OS, reducing overhead.

• Hardware Virtualization

• Operating System Visualization

• Network Virtualization

• Storage Virtualization

This abstracts physical network resources into logical units. This ensures the efficient sharing of physical network resources among VMs.

• Hardware Virtualization

• Operating System Visualization

• Network Virtualization

• Storage Virtualization

This combines or abstracts physical storage resources. Hence, it results in efficient resource management and scaling.

• Operating System Visualization

• Network Virtualization

• Storage Virtualization

A _______ like Docker is a key component of storage virtualization. What is the word and what is its definition?

• Container - provides isolated environments for running applications.

• Hypervisor - A layer that virtualizes hardware to allow multiple operating systems to run on a single physical machine.

• Virtual Storage Manager - A tool that abstracts and manages physical storage into logical storage pools.

• Network Adapter - A device or software component that connects a computer to a network.
