Definition cloud computing
1. There is not one definition of cloud computing.
2. Every one can use the name.

WikipediaCloud computing is Internet ("cloud") based development and use of computer technology ("computing").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 "in the cloud" 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

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.

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

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

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

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