1

Programming that handles very low-level interaction among hardware and software, such as task scheduling, allotment of time and resources, etc

Supervisor

2

Extra layer of sophisticated programming required by full virtualization that manages the vastly more complex interactions

Hypervisor

3

Paid hypervisor compatible with Windows and Linux

VMware

4

Free hypervisor compatible with Windows, macOS, and Linux

Oracle VirtualBox

5

Microsoft’s free hypervisor for Windows

Hyper-V

6

Linux’s free hypervisor

KVM

7

Software or hardware that converts the commands to and from the host machine into an entirely different platform

Emulator

8

Running a virtual machine on your local system regardless of whether the VM file itself might be stored locally or on a central server accessed via the network

Client-Side Virtualization

9

Extra features in CPUs to support hypervisors; Intel’s VT-X and AMD’s AMD-V

Hardware Virtualization Support

10

Every VM running on that one hypervisor will act as though it is connected to its own switch and nothing else

Internal Network

11

A VM with this accesses the same network as the host system; a lot like the VM has its own cable to connect it to the network. The default when you create a new VM

Bridged Network

12

Switch created by the VM to connect VMs together

Virtual Switch

13

Removing the host OS altogether and installing nothing but the hypervisor to improve performance. No software between it and the hardware. Also known as Type-1

Bare-Metal Hypervisor

14

Applications such as VMware Workstation

Type-2

15

Large-scale global providers use virtualization to minimize idle hardware, protect against data loss and downtime, and respond to spikes in demand. Example: Amazon Web Services (AWS)

Infrastructure as a Service (IaaS)

16

Provider gives programmers all the tools they need to deploy, administer, and maintain a Web application. The provider starts with some form of infrastructure, which could be provided by an IaaS, and on top of that the provider builds a platform: a complete deployment and management system to handle every aspect of a Web application. The infrastructure underneath this is largely invisible to the developer

Platform as a Service (PaaS)

17

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

Software as a Service (SaaS)

18

Software, platforms, and infrastructure delivered through networks that the general public can use

Public Cloud

19

Business-owned, internal cloud that is created if a business wants some of the flexibility of the cloud, needs complete ownership of its data, and can afford both

Private Cloud

20

Like a private cloud paid for and used by more than one organization. Not run by a city or state for citizens’ use, it is a group of organizations with similar goals or needs

Community Cloud

21

A cloud that connects some combination of public, private, and community clouds, allowing communication between them

Hybrid Cloud

22

Technique that means not having to maintain a private cloud powerful enough to meet peak demand - an application can grow into a public cloud instead of grind to a halt

Cloud Bursting

23

The ability to expand the number of servers, even spread them out geographically

Rapid Elasticity

24

With cloud computing, it’s easy to set up your application to add or reduce capacity based on demand

On-demand

25

Consolidating systems’ physical and time resources

Resource Pooling

26

Regardless of how costs are measured (traffic that goes in and out of your web application or the time that every one of your virtualized servers is running), it differs from more traditional hosting with a fixed monthly or yearly fee

Measured Service

27

Some companies charge by the amount of processing resources used, such ad CPU usage. Enables very careful monetizing of resources used. You pay for what parts of the hardware you use, rather than a more general fee for all the hardware of a system

Metered Service
