What is cloud computing? Nowadays, many companies are changing their overall information technology strategies to embrace cloud computing in order to open up business opportunities. There are numerous definitions of cloud computing. Simply speaking, the term “cloud computing” comes from network diagrams in which cloud shape is used to describe certain types of networks. All the computing of more than one computer via a network or the service gained from the host computer via a network is considered cloud computing. Through different types of devices such as PCs, smart phones users can access to services and computing resources in clouds. According to the National Institute of Standards and Technology (NIST), ‘‘Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction’’. Cloud computing represents a convergence of two major trends (IT efficiency and business agility) in information technology. The term IT efficiency refers to using computing resources more efficiently through highly scalable hardware and software resources. Furthermore, the business agility is the ability of a business to use computational tools rapidly, to adapt quickly and cost efficiency in response to changes in the business environment. Cloud computing can remove traditional boundaries between businesses, make the whole organization more business agile and responsive, help enterprises to scale their services, enhance industrial competitiveness, reduce the operational costs and the total cost of computing, and decreases energy consumption. It would seem that cloud computing can provide new opportunities for innovation by allowing companies to focus on business rather than be stifled by changes in technology.
