Flashcards in Chapter 16: Virtualization and Cloud Computing Deck (18):
1

Virtual Machine

Special software running on a computer to create a complete environment that imitates all of the hardware you'd see on a real computer.

2

Hypervisor

A layer of programming that creates, supports, and manages a virtual machine.

3

Benefits of VMs

-Power Saving
-Hardware Consolidation
-System Recovery

4

Bare-Metal Hypervisor

A hypervisor that does not run atop an OS

5

3 Bare-Metal Hypervisors

1) vSphere
2) Hyper-V
3) XenServer

6

Storage Area Network (SAN)

A server that can take a pool of hard disks and present them over the network as any number of logical disks.

7

Fibre Channel (FC)

A self-contained, high-speed storage environment with its own storage arrays, cables, protocols, and switches.

8

Network Attached Storage (NAS)

A dedicated file server that has its own file system and typically uses hardware and software designed for serving and storing files.

9

Virtual Switch

Special software that enables VMs to communicate with each other without going outside of the host system.

10

Virtual Router

A router that is implemented in software within a virtual machine.

11

Virtual Firewall

A firewall that is implemented in software within a virtual machine in cases where it would be difficult, costly, or impossible to install a traditional physical firewall.

12

Control Plane

Makes decisions about how to move traffic

13

Data Plane

Responsible for executing decisions made by the control plane

14

Software Defined Networking

Cuts the control plane of individual devices out and lets an all-knowing program called a network controller dictate how both physical and virtual network components move traffic through the network.

15

Infrastructure as a Service (IaaS)

Providing servers, switches, and routers to customers for a set rate. Basically virtualization capabilities without having to purchase hardware.

16

Platform as a Service (PaaS)

A complete deployment and management system that gives programmers all the tools they need to administer and maintain a Web application

17

Software as a Service (SaaS)

Provides access to necessary applications wherever you have an Internet connection, without having to carry data with you or regularly update software. Google Maps etc.

18

Public Cloud

Software, platforms, and infrastructure that the general public can use.
