Cloud Computing Based on Service-Oriented Platform

Cloud computing is a recent concept for using Information and Communications Technology (ICT), in which ICT resources, such as servers and storage devices, existing in the Cloud (Internet) are used via a network. It offers the following advantages to customers: They do not need to prepare servers or other hardware; they can use it whenever they want using only the required resources; they can access virtually unlimited computing power; they can easily interconnect systems; and they do not need to own facilities, which leads to green computing.
