Presentation on cloud computing and impact of IT on organization.

1. Cloud Computing
&
Impact of IT on
organization

2. Cloud Computing
• Cloud computing is computing in which large groups
of remote servers are networked to allow centralized
data storage and online access to computer services
or resources

3. Characteristics
• Agility
• Application Programming Independence
• Cost
• Device and location Independence
• Maintenance
• Performance
• Productivity
• Reliability
• Elasticity

4. Types of clouds
Public Cloud
• Computing infrastructure is hosted by cloud vendor at the
vendors premises.
• and can be shared by various organizations.
• E.g. : Amazon, Google, Microsoft, Sales force
Private Cloud
• The computing infrastructure is dedicated to a particular
organization and not shared with other organizations.
• more expensive and more secure when compare to public
cloud.
• E.g. : HP data center, IBM, Sun, Oracle, 3tera

5. Hybrid Cloud
• Organizations may host critical applications on private clouds.
• where as relatively less security concerns on public cloud.
• usage of both public and private together is called hybrid
cloud.

6. Cloud service models
Software as a Service (SaaS):
• It is an application that can be accessed from anywhere on
the world as long as you can have an computer with an
Internet Connection.
• We can access this cloud hosted application without any
additional hardware or software.
• E.g. : G-mail, Yahoo mail, Hotmail etc.

7. Advantages of Consuming SaaS
•Typically more powerful & secure than in
house operations
•Has a low cost of ownership and frees up
I.T. space.
•Applications being offered are typically
good or else people would find business
else where.

8. Platform as a service (PaaS):
• gives us nice API (Application Programming Interface) and
take care of the implementation.
• In the PaaS model, cloud providers deliver a computing
platform and/or solution stack typically including operating
system, programming language execution environment,
database, and web server.
• is a platform for developers to write and create their own
SaaS i.e. applications.
• E.g.: Google App engine, Windows Azure etc.

9. Advantages of Consuming PaaS
•Each platform component is provided as a
service.
•The services it has the functionality to
support a complete life cycle of developing
and completing web applications .
•Has the ability to host, maintain, test in its
own integrated development environment

10. Infrastructure as a service(IaaS)
• Infrastructure as a Service is a provision model in which an
organization outsources the equipment used to support
operations, including storage, hardware, servers and
networking components.
• cloud providers offer computers – as physical or more often as
virtual machines – raw (block) storage, firewalls, load
balancers, and networks

11. Advantages of Consuming IaaS
• It is a metered service, you pay for what
you use.
•Dynamic scaling that allows you to pool
your resources accordingly.
•Good investment for smaller companies
that can’t afford a full networked
infrastructure.
•Allows current IT team to shift focus
onto more important issues.

12. The table below is showing a comparison among
the 3 cloud computing service models:

13. Impact of IT on Organization
Information technology (IT) is dramatically changing the
business landscape. IT significantly affects strategic options
and creates opportunities and issues that managers need to
address in many aspects of their business.

14. some of the key impacts of technology on
organizations are;
• Business Strategy:
IT creates new opportunities for innovation in products
and services. Services which used to be delivered in
person can now be delivered over networks.
• Organization Culture:
Newer types of IT such as electronic mail and groupware are
creating significant changes in the way that information flows
around group ware, and between them and their customers
and suppliers. It can hasten the development of more open
and innovative cultures

15. • Management Process:
IT is rapidly entering the era where it supports unstructured
management processes as well as highly routinized business
processes. It provides more effective ways of accessing
information from multiple sources, including use of external
information on databases and the Internet.
• Work:
IT is dramatically changing the nature of professional work.
Becoming effective not only requires traditional skills of
organizing, thinking, writing etc., but knowing how best to
use the power of IT for researching sources, accessing
information, connecting to experts.

16. • Economic Impacts:
From the point of view of economics, IT changes both the
relative costs of capital and the costs of information.
Information systems technology , especially the use of
networks, can help firms lower the cost of market
participation, making it worthwhile for firms to contract with
external suppliers instead of using internal sources.
