Cloud Computing is a fairly new internet service structure. it provide ways to virtually map physical storage, internet access together with a web based application for a remote user. The advantage of cloud computing is the reduction in the amount of server and energy needed to run a large scale service.
the idea of cloud computing resides in thinking of whole bunch of servers running for different services as a cloud, instead of independently running machines. It virtuallizes all physical machines into several layers: infrastructure service layer, platform service layer, and software service layer.
infrastructure service layer manages web throughput and storage space for remote server, giving each remote client a fixed network power and storage space without having all those service being tied down to one service machine. it also provide ways to run a operating platform on top of the infrastructure layer, limiting the storage and service to specific platforms that uses it.
the platform service layer provide users a selection of applications they could use. an example of platform service is the google application engine
the software service layer contains web applications the user may use, one example would be Google Apps.
