Cloud computing is a computing model based on a large number of network resources, and is a "readily available, on-demand" service delivery and usage patterns. The core idea of cloud computing is to provide computing resources in the form of service, and as a representative of the new generation of information technology, cloud computing can make full use of the computational storage and application resources of the past investment, reduce the cost of energy consumption and it operation, improve the efficiency and performance of the system. Cloud computing can help organizations meet the needs of fast-changing and innovative upgrades of highly scalable and highly available organization business with lower inputs.

Cloud computing application is an urgent requirement for enterprises to deal with the change of economic environment. Large enterprises are the main force of China's participation in economic globalization competition, in the current post-financial crisis era, the global market is still in a period of volatility, enterprises need to maintain their adaptability in the changing environment, rapid response to the market competition in the business process of customer demand changes, at any time to meet the requirements of new market opportunities, Build continuous innovation capability.

Cloud computing application is an inevitable requirement for enterprises to assume social responsibility. With increasing global energy intensity and increasing environmental pollution, China has proposed to accelerate the transformation of economic development mode and strategic adjustment of economic structure, promote social sustainable development, construct low-carbon Environmental protection IT environment by applying scientific and technological innovation, and become an enterprise to integrate social development objectives into the company's business mode and mitigate negative impacts on the environment, Part of fulfilling social obligations.

The application of cloud computing is the objective requirement of business model innovation with the help of information technology. The rapid development of hardware technology such as chip makes the hardware capability soar, and the virtualization technology makes these hardware resources can be effectively segmented and managed. The service-oriented architecture makes Open data model and communication standard more and more widely used by enterprises, and provides feasible scheme for innovation Resources and service organization mode. To provide hardware and software resources in the form of services to reduce IT costs to ensure quality of service support business innovation is possible.

As the leading information Technology service company in China, Sadie consultants rely on China's electronic Information Industry Development Research Institute (Sadie Group) A strong resource platform, based on the Enterprise cloud computing in-depth research, through the analysis of the development of enterprise Cloud environment application value development and enterprise cloud technology framework to the reader sketch out the overall outline of the enterprise cloud, Based on the application of typical scenario architecture and best practice cases, this paper studies the key applications of cloud management in different fields, and puts forward the construction steps and strategies of enterprise cloud, which provides a reference for promoting the application and construction of enterprise cloud.

Sadie Consultant thinks: Enterprise Cloud from overall can divide into three layer architecture, is the infrastructure Layer IaaS platform layer PAAs and application tier SaaS respectively. The cloud architecture organically integrates hardware and software resources in the cloud through virtualization and automation, and delivers services from the cloud across the network to users. The infrastructure layer is a collection of virtualized hardware resources and related management features. The hardware resources of the cloud include computing storage and network resources. Between the infrastructure layer and the application layer, the platform layer is a collection of universal and reusable software resources, which provides the environment for the development, operation, management and monitoring of cloud applications. The application layer is a collection of applications built on top of the resources provided by the infrastructure layer and delivered to the user over the network.

According to Sadie Consultant's research, with the development of cloud computing, enterprise business model of continuous innovation, enterprises in the organizational structure of the marketing model of the value chain will gradually occur a significant or even qualitative changes. Production and manufacturing power Energy Telecom Operation Logistics Retail building construction industry, respectively, to create cloud power Cloud Telecom Cloud Logistics Cloud video cloud, such as the focus of application.

1 under the background of the country advocating vigorously developing the strategic emerging industries, the manufacturing industry is facing the transformation of the traditional mode to the service-centered new business model. Manufacturing cloud with advanced cloud technology, to achieve the product development, production and sales after-sales service, such as the whole lifecycle of the integration of related resources to provide standard specifications can be shared manufacturing services Manufacturing mode. Manufacturing cloud emphasizes the use of information technology to integrate various manufacturing resources and to provide users with standardized services through virtualization technology. The manufacturing cloud supports manufacturing services that provide high value-added, low-cost and global manufacturing in a wide range of network resource environments.

2 power system is a super system with distributed characteristics in space, the power production control requires the high reliability of real time, and the production management of electric power naturally forms a set of "Hierarchical management control distributed processing" system. The power system cloud computing, through the cluster application of distributed computing and other system functions to the power system in the network of almost all network and computing applications together to work together to the various levels of power grids and terminals to provide data storage and computing services. Through the power cloud, a very short period of time can handle huge information to reach the level of supercomputer service.

3 Telecom operators face the pressure of energy saving and reducing consumption to improve service quality and business innovation, and the advent of cloud computing technology provides a new way to solve these pressures. Based on efficient virtual computing resources, applications can deliver high quality services in a flexible and secure manner that enables rapid scaling and scaling.

4 The logistics industry's business is inherently global in nature, and often has a series of heterogeneous IT systems operating, and these systems are probably not interoperable, which is bound to increase it costs significantly. Logistics cloud for the logistics hub of large logistics enterprises and all kinds of integrated enterprise logistics departments to provide services, rely on large-scale cloud computing processing capabilities of the standard operating procedures flexible business coverage of the precise link control intelligent decision-making support and in-depth information sharing to complete the logistics industry in all aspects of the information required.

5 China's Construction industry safety monitoring System automation and information level generally low, cloud computing highly scalable high reliability and highly flexible advantages, for the development of a new generation of distributed construction industry security monitoring system provides a brand-new idea. The video cloud integrates the knowledge of computer image processing pattern recognition, artificial intelligence and automatic control in cloud sensing network, and uses computer vision and video analysis method to analyze the camera's recording image sequence automatically. To realize the remote real-time image monitoring and management for the Environment protection field of construction project in safe construction site.

Combined with the consulting experience of group Enterprise Informatization Construction, Sadie Consultant put forward four steps of enterprise cloud Construction: cloud computing planning IT Management system construction of cloud computing standard system and implementation of key cloud computing project. In the Enterprise cloud construction, first completes the cloud computing plan, the enhancement informationization strategic management level, secondly must fully realize the IT control system the importance, the enhancement enterprise cloud construction leadership and the execution ability, guarantees the Enterprise cloud Computing Plan project construction implementation; Third, we must pay attention to explore the enterprise Cloud standard system construction, Realize the sustainable development of information project through cloud realization of enterprise's business cooperation and integration operation; Finally, we should grasp the key project construction of enterprise cloud tightly, promote the integration and transformation of business system through key projects, do well the management and control intelligent decision of integrated manage business, and cloud the key system of the main data management system Safeguard the informatization work to advance smoothly for a long time.
