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.

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

14. PROGRAMS.

Purchase programs.

Load to the computer.

Each computer would need the program loaded and stored on the


Allows your content to become handy.

Save to the storage device.

Take device to any compatible computer.


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.
