4. WHAT IS CLOUD COMPUTING?
4
VMware, the global leader in virtualization and global infrastructure tells,
Cloud computing is a new approach that reduces IT complexity by leveraging the
efficient pooling of on-demand, self-managed virtual infrastructure, consumed as a
service.
(http://www.vmware.com/ap/cloud-computing.html)
5. ACCORDING TO WIKIPEDIA.
5
Cloud computing is Internet-based computing, whereby shared
resource, software, and information are provided to computers and
other devices on demand, like the electricity grid.
(http://en.wikipedia.org/wiki/Cloud_computing)
6. SERVICES OF CLOUD COMPUTING.
SOFTWARE AS A SERVICE (SaaS).
PLATFORM AS A SERVICE (PaaS).
INFRASTRUCTURE A AS SERVICE (IaaS).

7. SOFTWARE AS A SERVICE.
7
Software as a Service (SaaS) is a software distribution model in
which applications are hosted by a vendor or service provider and made available
to customers over a network, typically the Internet.
8. PLATFORM AS A SERVICE.
8
PaaS(Platform as a service), as the name suggests, provides you
computing platforms which typically includes operating system, programming
language execution environment, database, web server etc.
9. INFRASTRUCTURE A AS SERVICE.
9
IaaS(Infrastructure as a service), as the name suggests, provides
you the computing infrastructure, physical or (quite often) virtual machines and
other resources like virtual-machine disk image library, block and file-based
storage, firewalls, load balancers, IP addresses, virtual local area networks etc.
10. THE CLOUD REQUIRES.
An Internet connection
An account - Created with a user name and a password.
Agree to Terms

12. COMPUTER STORAGE.
12
Computers have internal or hard drive storage(C: Drive)
CPU has a drive for storing programs, documents, pictures, videos,
presentations, etc…
Standard Computer Tower
or Central Processing Unit
(CPU)
Inside the Computer
13. INTERNAL STORAGE.
Content is stored on THAT computer.
To use content must return to THAT computer.
Cannot access this content from another device or computer.
13
15. EXTERNAL STORAGE.
15
Allows your content to become handy.
Save to the storage device.
Take device to any compatible computer.
Open and use content.
CD/DVD
Thumb Drive
SD Card
External Hard Drive
Micro SD Card
16. NETWORKED STORAGE.
Multiple work stations talk to one unit that stores information and
data.
Data is not saved to the C: drive, but to a network drive.
Can retrieve the data stored to the network from any of the
connected workstations.
16
17. SAVING DOCUMENTS.
17
When you do a “save as” on your computer, you choose where to
save the material.
Internal Storage
External Storage
Network
18. CLOUD STORAGE.
Create an Account – User name and password.
Content lives with the account in the cloud.
Log onto any computer with INTERNET to find your content.
18
19. DOWNLOADS FOR STORAGE.
Download a cloud based app to a computer you own.
The app lives on your Computer.
Save files to the app.
When connected to the Internet it will sync with the cloud.
The Cloud can be accessed from any Internet enabled PC.
19
20. SAVE FILE AS.
Do “save as” to save a file to your computer and the cloud.
The syncing folders makes data retrieval easier.
Box and DropBox require this download to work.
20
21. UPLOAD DOCUMENTS.
Log-in to the online storage account.
Click upload a file.
Find the folder on hard drive, network, or external storage.
21
Upload to cloud storage.
2 GB
5 GB
7 GB
5 GB
33. ADVANTAGES.
Can be less expensive compared to buying software and hardware.
Can be used from any computer or device with an Internet
connection.
The device does not need as large of an internal storage system.
Compatible with most computers and operating systems.
Updates occur across the service.
