3. Utility Computing Utility Computing is the packaging of computing resources, such as computation, storage and services, as a metered service similar to a traditional public utility (such as electricity, water, natural gas, or telephone network). http://en.wikipedia.org/wiki/Utility_computing

4. Service Is software a product or a service? So from the legal perspective software is really a product. I mean, a service. Sorry for this lapse. http://en.wikipedia.org/wiki/Service_(economics) http://se.ethz.ch/~meyer/publications/softdev/product-service.pdf

5. SaaS Software as a service is software that is deployed over the internet and/or is deployed to run behind a firewall on a local area network or personal computer. http://en.wikipedia.org/wiki/Software_as_a_Service

9. The Network is the computer The network will truly be the computer. Google's CEO, Eric Schmidt, The Economist, 2006 Gilder’s Law: Bandwidth grows at least three times faster than computer power. George F. Gilder http://googlesystem.blogspot.com/2006/11/network-will-truly-be-computer.html http://en.wikipedia.org/wiki/George_Gilder

10. The Network Effect Metcalfe's law: Network value rises by the square of the number of terminals. Robert Metcalfe Metcalfe's law characterizes many of the network effects of communication technologies and networks such as the Internet, social networking, and the World Wide Web. http://en.wikipedia.org/wiki/Robert_Metcalfe http://en.wikipedia.org/wiki/Metcalfe's_law

26. Capacity vs Usage

27. Category of Cloud Computing Public Cloud – The public cloud is standardized cloud computing where all resources like applications and storage is made available to general public over the internet by services provider itself, which offers it free of cost or pay-per use basis. Hybrid Cloud – Hybrid cloud can be defined as use of both physical hardware and virtualized cloud server instance together to provide a single common service. Two separate clouds joined together or combination of virtualized cloud server instances used together with real physical hardware is also known as Combined cloud. Private Cloud – Private cloud provides hosted services to a limited number of people, may be within the cooperation, behind a firewall and it is also called internal cloud.
