4. Example of Cloud Computing
Google Apps: provides the service of business applications such as Gmail,
Google Talk, Google Calendar and Google Docs, etc.
 Amazon Web Services: The services offered are the Amazon EC2 ,
Amazon S3, Simple DB , Amazon SQS .
 Azure: Microsoft provides operating system services, hosting, systems
development.

11. Software as a service (SaaS)
This is the most common form
of cloud computing which we
see in action. It is a complete
software offering on the
cloud. They are accessed by
the customers on pay per use
basis.
Example:Gmail , Hotmail etc

12. Platform as a service (PaaS)
The consumer creates the
software using tools and
libraries from the provider.
The consumer also controls
software deployment and
configuration settings. The
provider provides the
networks, servers and storage
.
Example:Wavemaker,Longjump etc

13. Infrastructure as a service
(IaaS)
Hardware related services are
provided using the principles
of Cloud Computing. These
include disk storage and
virtual servers.
Amazon EC2, Amazon S3,
Rackspace Cloud Servers are
some of the leading vendors.

14. Cloud Computing classified basis of
location
•
•
•
•
Public Cloud
Private Cloud
Hybrid Cloud
Community Cloud

15. Public Cloud
Computing infrastructure is hosted at
the vendor’s premises. The customer
has no visibility over the location of
the cloud computing infrastructure.
The computing infrastructure is
shared between organizations.

16. Private Cloud
Computing architecture
is dedicated to the
customer and is not
shared with other
organisations.Private
clouds may be externally
hosted ones as well as in
premise hosted clouds.

17. Hybrid Cloud
Organisations host some
critical, secure
applications in private
clouds. The not so critical
applications are hosted in
the public cloud. The
combination is known as
Hybrid Cloud.

18. Community Cloud
The
cloud infrastructure is
shared between
the organizations of
the same community.

19. 1. Public Cloud - A public cloud can be accessed
by any subscriber with an internet connection
and access to the cloud space.
2. Private Cloud - A private cloud is established
for a specific group or organization and limits
access to just that group.
3. Community Cloud - A community cloud is
shared among two or more organizations that
have similar cloud requirements.
4. Hybrid Cloud - A hybrid cloud is essentially a
combination of at least two clouds, where the
clouds included are a mixture of public, private,
or community

20. Benefits
- Reduced hardware software cost
-Reduced maintenance cost
-High performance
-High reliability
-High scalable on demand
-Multi tenancy
-Batter security
- Virtualization

21. Disadvantages
Security Issues
Terms of Service
Privacy Policies

22. Conclusion
• Clouds
 Provide internet based services
 Available on demand
 And fully managed by the provider
 There is no one “Cloud”. There are many models and
architectures
• Clouds let you
 Avoid capital expenses on hardware, software, and service
 Share infrastructure and costs
 Lower management overhead
 Access a large range of apps

23. Conclusion
Like everything else, cloud
computing too has its pros
and cons. While the
technology can prove to
be a great asset to your
company, it could also
cause harm if not
understood and used
properly

24. Green benefits of Cloud Computing
Servers
 Reduce the number of servers : 5 to 10 virtual servers to
1 physical server
 Less space required
 Reduced power
 More energy efficient servers
Workstations
 Thin clients -> reduced power ,
 Virtual workstations running on servers : 30 to 70 wks to
1 server
IT Support
 Workstations that are not used are switched off,
 Maintenance performed real time.
Environmental  Lower carbon emissions : less power needed
 Recycle old equipment

25. Preparing for the Future
Sampling of IT skills likely to be in demand in the future
– Functional application development and support
• I.e. Oracle, SAP, SQL, linking hardware to software
– Leveraging data to make strategic business decisions
• I.e. Business Intelligence : Applying sales forecasts to inventory and manufacturing
decisions
– Mobile apps
• Android, iPhone, Windows Mobile
– WiFi engineers
• USF to include broadband communications (LTE replaces GSM/CDMA)
– Optical engineers
• Optical offers the highest bandwidth today (PON, CWDM, DWDM)
– Virtualization Specialists
• Economies of scale require virtualization (server, storage, client…)
