03 - Cloud Storage

 1. What is cloud computing?

  Storing our data online instead of on our own hard drive

  Downloading data to the clouds in the sky

  Storing our data offline instead of online

  Storing RAM on an online server

 2. What are the advantages of cloud computing?
1) You can access your files wherever you are, if there is an internet 
connection and a device with which you can view and edit them.

2) It will provide you with a faster internet speed.

3) It is always free, i.e. no cost.

 3. What are the disadvantages of cloud computing?
1) Occasional downtime during which you will not be able to access 
any of your applications, server or data from the cloud.

2) You can only control and manage the data and applications. 

3) Data is vulnerable if the login details are compromised.

 4. Is the following statement true or false…
Private cloud storage is a type of storage mechanism that
stores an organization's data at in-house storage servers
by implementing cloud computing and storage technology.



 5. Which of these are advantages of private cloud storage?
1) Efficiency and control as the private cloud storage is hosted either
on site or a privately hosted environment.

2) High level of customisation - you can choose the infrastructure with 
specific storage and networking characteristics, so the system meets 
your individual needs perfectly.

3) Has a greater level of security compared to public cloud 
storage as all data is saved and managed on servers that cannot be 
accessed by the public.

 6. Cloud storage includes the storage of mice and keyboards as well as other physical devices in a physical 'cloud' (or shelf).



 7. Is the following definition of public cloud storage true or false?
This is a cloud service that requires little administrative controls and 
can be accessed online by any anyone you authorise. You get the same 
security but don’t need to maintain the system as much as you would with 
a private cloud.



 8. Is the following statement an advantage of public cloud storage?
Virtual machines within a Public Cloud system can be created, 
scaled and shut-down in an instant. A Public Cloud service can 
therefore easily scale to meet any changes in your needs -
perfect for ISVs with rapidly changing demand.



 9. What are the three main types of cloud computing services available?

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

  Software as a Service (SaaS), Platform as a Symbol (PaaS), Infrastructure as a Service (IaaS)

  Software as a Symbol (SaaS), Platoon as a Service (PaaS), Infrastructure as a Symbol (IaaS)

  Software as a Symbol (SaaS), Platform as a Symbol (PaaS), Infrastructure as a Service (IaaS)

 10. What is Software as a Service (SaaS)?

  Cloud-based software infrastructure that is run on remote computers owned and maintained by a cloud company. The Internet and usually a web browser are used to connect the user’s computer or mobile device to the cloud computer.

  Applications that help maintain your current storage space

  Software that allows you to reduce your storage space

  Cloud-based software applications are run on remote computers owned and maintained by a cloud company. The Internet and usually a web browser are used to connect the user’s computer or mobile device to the cloud computer.

 11. State an example of SaaS?


  Windows OS

  Microsoft Word

  Google Gmail

 12. What are the benefits of SaaS?
1) No software to install or maintain - this is done by the provider.
2) It can be used immediately after signing up.

  1 & 2

  Neither are benefits



 13. What is PaaS?

  A cloud-based environment used by software developers and web developers. The cloud company provides the hardware (network, servers, storage) and tools to help in building applications, so the user can create and control software and software settings.

  An environment used to develop security software

  A service that provides downloadable applications developed by other users

  A service to create your own platforms

 14. What is IaaS?

  Cloud computing that has available space that can be bought permanently

  A service to build your company infrastructure

  Cloud computing that provides companies with resources on a pay-per-use rental basis. So, a company only pays for the servers and storage space that it uses.

  An infrastructure that acts as your backup data storage

 15. True or false?
With cloud storage, if you do not have internet access you cannot
update your files.
