A+ Core 1 Virtualization and Cloud Computing: Cloud Computing Concepts

What are the three most common types of cloud computing services?

-Infrastructure as a Service (IaaS) -Platform as a Service (PaaS) -Software as a Service (SaaS)

What is the main benefits of using the public cloud?

-Low (or zero cost) -Scalability -Reliability -Flexibility

Many of the clouds in existence today are owned by big companies. List a few of these big companies?

-Microsoft -Google -Amazon -Apple

Cloud-based file storage services allows a users to store their files in the cloud. Give three examples of popular cloud-based file storage services.

1. Dropbox 2. Microsoft OneDrive 3. Google Drive

Give two examples of popular cloud-based off-site email applications.

1. Microsoft Outlook 2. Gmail

There are different types of clouds that are used by an organization...there are four main types...what are they?

1. Private cloud 2. Public cloud 3. Hybrid cloud 4. Community cloud

Give a common example of resource pooling.

A VM (Virtual Machine) manager using a portion of available physical memory is using resource pooling

Which cloud-based application enables smartphones and tablets (i.e., mobile devices) to run apps that were originally developed for Windows desktop operating systems?

Applications for cell phones/tablets

What method allows you to access remote Servers to store files or run applications?

Cloud computing

What type of cloud was created so that multiple organizations with common interests can combine to create a cloud?

Community cloud

Which type of cloud is basically a private cloud that is paid for by a group of organizations in the same industry or with similar challenges?

Community cloud

Which type of cloud is like a public cloud but with better security, where the client knows who the other clients are and, in theory, can trust them more than they can trust random people on the Internet?

Community cloud

If the public doesn't own the public cloud, then who does?

Companies such as: -Google -Amazon -Apple -Microsoft etc.

One of the benefits of cloud computing is how it enhances the concept of shared resources. All networks feature shared resources such as storage, data, servers, but with cloud computing, these resources can be accessed via the Internet (external/public), not just those connected to the same LAN (internal/private). One of the keys to sharing resources is understanding what you can do with internal and external cloud resources. Which type of shared resource—either internal or external—shares its resources with a public cloud and has underlying infrastructure owned by a third-party (i.e., Google, Microsoft, Apple, etc.)?

External cloud

True or False: Private clouds use shared resources?

False

True or False: There is only one commercial cloud in existence today?

False...there are hundreds of clouds in existence today

What type of cloud gives the client the great features of a public cloud while simultaneously allowing for the storage of more sensitive information on the private cloud?

Hybrid cloud

What type of cloud is a mixture of a public cloud and a private cloud?

Hybrid cloud

This type of cloud computing service provides the computing platform, but no additional software. The user will usually configure the platform with the appropriate CPU, memory, and storage options, and the service provider is only responsible for the uptime and availability of the hardware platform. The user is generally responsible for all software administration. Which type of cloud computing service is this?

Infrastructure as a Service (IaaS)

Which cloud computing service provides hardware, but still requires the user to setup, configure, and manage the operating system and applications?

Infrastructure as a Service (IaaS)

Which type of cloud computing service allows an organization to move their entire infrastructure to the cloud? Infrastructure includes items such as Routers, Switches, Firewalls, and Servers.

Infrastructure as a Service (IaaS)

Which type of cloud computing service provides hardware to be used in the cloud, and it's the responsibility of the customer to install operating systems, applications, and data; hardware is available as a on-demand resource?

Infrastructure as a Service (IaaS)

One of the benefits of cloud computing is how it enhances the concept of shared resources. All networks feature shared resources such as storage, data, servers, but with cloud computing, these resources can be accessed via the Internet (external/public), not just those connected to the same LAN (internal/private). One of the keys to sharing resources is understanding what you can do with internal and external cloud resources. Which type of shared resource—either internal or external—doesn't share it resources, allows you to build your own cloud, and has no ongoing costs?

Internal cloud

What is a Virtual desktop?

Is simply a desktop environment on a virtual machine

What is virtualization? Give the BEST example.

Is when a simulation of something is created that behaves in the same manner as the real thing; An example is a Virtual Machine (VM), which looks and behaves like a real computer and operating system

What big advantage is allowed through a company using a private cloud?

It allows a company to control its own security

What is cloud computing?

It's a way of offering on-demand services that extend the capabilities of a person's computer or an organization's network

Which cloud computing feature monitors cloud resources that customers use and bills them accordingly?

Measured service

Which cloud computing feature can work in conjunction with the measured service feature, and is measured based on usage; as more information is uploaded, stored, and downloaded, the costs are tracked and billed accordingly? In other words, you pay for what you use.

Metered service

Which cloud computing feature allows administrators the ability to instantly create, modify, or delete services; provides the flexibility to build an application infrastructure for any service at any time?

On-demand service

Which cloud computing feature allows the users to create or remove resources at any time?

On-demand service

Which important cloud computing feature is one of the cloud's best features from an end user's stand-point in that it allows users to access additional storage, processing, and capabilities automatically and at any time you'll need it without requiring intervention from the service provider?

On-demand service

This type of cloud computing service adds a layer to IaaS that includes software development tools such as runtime environments. Because of this, it can be very helpful to software developers, and they are free to focus on building their application and scaling it. Which type of cloud computing service is this?

Platform as a Service (PaaS)

Which cloud computing service provides the building blocks for application developers?

Platform as a Service (PaaS)

Which type of cloud computing service provides a hosted application framework in the cloud, and the customer is responsible for developing their own application based on the cloud-based framework?

Platform as a Service (PaaS)

Which type of cloud computing service provides various software solutions to organizations, especially the ability to develop and test applications in a virtual environment without the cost or administration of a physical platform?

Platform as a Service (PaaS)
