Cloud as an alternative to green computing

2. Introduction
• Cloud computing is a type of
computing that relies on
sharing computing resources
rather than having local
servers or personal devices to
handle applications.
• Green computing is the
environmentally responsible
and eco-friendly use of
computers and their resources

3. Topics
• Introduction
• Why cloud is green?
• Efficiency Model
• Facts & Figures
• Conclusion
• Future Scope

5. Why cloud is green?
• Through the use of large shared servers and
storage units, cloud computing can offer
energy savings in the provision of computing
and storage services.

7. Data Center Energy Use
When companies use their dedicated data
centers they need to have a lot of resources
which primarily involves
• Air Conditioning unit.
• Dedicated Hardware.
• Resource Person
• Power Backup
• Security

8. Switching to the cloud would mean…
When the cloud is
implemented there is
only one server at one
data center which is
maintained by the
datacenter and this
server is used by many
corporations.

9. Transportation System Energy Use
• This involves the data transfer from
client system to main server and
back to the client.
• Moreover if data transfer needs to
take place between the nodes
itself, there is separate data transfer.
9

10. Switching to the cloud would mean…
There is direct transfer from client to server thus
saving energy that was wasted in transport. 10

11. Residential and Office Building appliance energy use
• The individual electrical appliances further used
leads to wastage.
No use of any extra appliances on the client side.
11

12. Business and Consumer Client device
Energy Use
• This is related to the fact that if data transfer
needs to be done from client to any other
device the entire data is transferred.
12

13. Whereas in cloud the data can be easily
accessed thorough any device. 13

14. Network Equipment Energy Use
• There is a lot of networking components
involved when there is a network of computers
in a building.
• Instead if we go for internet connection and
cloud architecture the energy can be saved.

15. Energy wastage by inefficient handling
Inefficiency in
handling leads
to energy losses

17. Conclusion
• Power consumption is decreased in cloud
computing.
• Private and public cloud storage services are
more energy efficient than storage on local
hard disk drives when files are only
occasionally accessed.
• There is an overall decrease in costs involved
in computing equipment for an organization.
17

18. Future Scope
• Cloud infrastructure will soon become the
default web server environment.
• With the increasing speed of internet and easy
availability cloud computing would be more
widely used.
