Cloud Computing
Michael Armbrust (2009) pointed out, Cloud Computing, the long-held dream of computing as a utility, has the potential to transform a large part of the IT industry, making software even more attractive as a service and shaping the way IT hardware is designed and purchased. Developers with innovative ideas for new Internet services no longer require the large capital outlays in hardware to deploy their service or the human expense to operate it.
Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS). The datacenter hardware and software is what we will call a Cloud. Any application needs a model of computation, a model of storage, and a model of communication. The statistical multiplexing necessary to achieve elasticity and the illusion of infinite capacity requires each of these resources to be virtualized to hide the implementation of how they are multiplexed and shared..
Tim O’Reilly (2009) believes that the future belongs to able to provide immediate information to users of services. Mobile is the key. Background in thedatacenteris a natural model to run in, especially those mashup integration type of service.
Business Model
Li Zhenyong (2010) thinks the business model is to maximize customer value, elements can make the enterprise run internal and external integration, form a complete set of efficient running systems with unique core competitiveness, and through the optimal form to meet customer needs, customer value, at the same time keeps the system reaching profit targets for the overall solution. Henning Kagermann, Weiying Zhang, Hubert Osterle (2010) considers that customer awareness of the value of a historical process of development, from the first cheap and fine products and services, to customers in the process of solution, is a gradual process of gradual close to the real requirements of the customer.
Amit and Zott (2008) describe the business model as an architecture configuration consisted of service elements. It’s designed to make the best use of business opportunities. The framework demonstrates the approach of network operating, composed of companies, suppliers, candidates and customers.
Another scholar Applegate (2010) considered the business model from the perspective of enterprise operating. He argued that business model is the demonstration of complicated business industry.
