Wikipedia
Cloud computing is Internet (quot;cloudquot;) based development and use of computer
technology (quot;computingquot;).It is a style of computing in which dynamically scalable and
often virtualised resources are provided as a service over the Internet.Users need
not have knowledge of, expertise in, or control over the technology infrastructure quot;in
the cloudquot; that supports them
The concept incorporates infrastructure as a service (IaaS), platform as a service
(PaaS) and software as a service (SaaS) as well as Web 2.0 and other recent (ca.
2007–2009) technology trends which have the common theme of reliance on the
Internet for satisfying the computing needs of the users. Examples of SaaS vendors
include Salesforce.com and Google Apps which provide common business
applications online that are accessed from a web browser, while the software and
data are stored on the servers.
The term cloud is used as a metaphor for the Internet, based on how the Internet is
depicted in computer network diagrams, and is an abstraction for the complex
infrastructure it conceals

6. Definition cloud computing
Marketspace
Cloud Computing represents a new way to deploy
computing technology to give users the ability to access,
work on, share it and store information using the Internet.
The cloud itself is a network of data centers - each
composed of many thousands of computers working
together - that perform the functions of software on a
personal or business computer by providing users
access to powerful applications, platforms and services
delivered over the Internet.

9. Everybody is using the cloud
• 1.5 miljard mensen verbonden met de
cloud.

11. Variants of the Clouds
• Companies host applications in the cloud that many users
User Level access through Internet Connections. The service being sold
or offered is a complete end-user application.
“software as a service”
Developer • Developers can design, build and test applications that run
on the Cloud provieder’s infrastructure and then deliver those
Level applications to end-users from the provider’s servers
“platform as a service”
• System administrators optain general processing, storage,
IT Level database, management and other resources and applications
through the network and pay only for what gets used.
“Infrastructure as a
service”

12. Not one Cloud?

13. Benefits and opportunities in the cloud
1. Anywhere/any time
2. Specization and customization of
applications build in cloud
3. Collaboration
4. Cost advantages
5. CO2 reduction
6. Cloud-enabled storage as a universal
service
7. Cloud-enabled processing power on
demand

14. Advantage of clouds

18. Full connectivity
2/3 off all Google
Searches in Asia are
through mobile devices
87 off all Google
Searches in Africa are
through mobile devices

19. Reliability

20. Security
1. Virus
2. Identity fraud
3. Patches
4. Expertise
5. Cyber-crime laws
6. Security breach / selling company

21. Privacy
1. Location where data stored
2. Location where you live in
3. Mission critical information
4. Routing of Internet
5. Audits/ data protection standards
6. Deleting information

22. Sustainability
Google Data centers Power comsumtion of
use 19% extra cooling datacenters is doubled
energy compared to in 2006 from 2000 and
the average of 96% will be four-fold in
2020.
World wide CO2 usage
of data centers
overtakes that of the
aviation industry.
