Cloud computing applications in large enterprises in China

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 high scalability, high availability, rapid organizational changes, and innovation upgrades with lower investment.

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 fluctuation, the enterprise urgently needs in the changing environment to maintain their adaptability, rapid response to the business process in the market competition environment, 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, with the increase of hardware capability, virtualization technology makes these hardware resources can be effectively segmented and managed, and the service-oriented architecture makes the Open Data model and communication standard more and more widely used by enterprises, and provides feasible scheme for innovating resources and service organization. Providing software and hardware resources in the form of services to reduce IT costs, ensure quality of service, and 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 corporate cloud development environment, application value, development status and corporate cloud technology framework to the reader outline of the corporate cloud, Based on the application overview, typical scenarios, architecture and best practice cases, this paper studies the key applications of cloud management in different fields, and puts forward the construction steps and implementation strategies of enterprise cloud, which provides a reference for promoting the application and construction of enterprise cloud.

The enterprise cloud can be divided into three tiers, namely, infrastructure layer IaaS, platform-level PAAs and application-level SaaS, according to Sadie. Cloud architectures organically integrate hardware and software resources in the cloud through virtualization, standardization, and automation, and deliver services from the cloud across the network to users. The infrastructure layer is a collection of virtualized hardware resources and related management features. The cloud's hardware resources 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 development, operation, management and monitoring environment for 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 the research of Sadie consultant, with the development of cloud computing, the continuous innovation of enterprise business model, the enterprise in the organizational structure, marketing model, value chain and so on will gradually occur significant or even qualitative changes. Manufacturing, power energy, telecommunications operations, logistics, retail, construction and other industries in the manufacture of cloud, power cloud, telecommunications cloud, logistics cloud, video cloud, etc. 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, sales, after-sales service and other life cycle of the integration of related resources, to provide standards, norms, shareable 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. Manufacturing Cloud supports manufacturing services that provide high value-added, low-cost and globalized manufacturing in a wide range of network resources.

2, the power system is a spatial distribution of the super system, power production control requirements of real-time, high reliability, power production management will naturally form a set of "Hierarchical management, hierarchical control, distribution processing" system. The power system cloud computing, through the cluster application, distributed computing and other system functions of 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 are facing the pressure of energy saving, improving service quality and business innovation, 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 is born with the characteristics of globalization, and often have a series of heterogeneous IT systems operating, and these systems are likely to be not interoperable, which will make it cost significantly increase. Logistics cloud for large logistics enterprises, logistics Hub center and all kinds of integrated enterprise logistics departments to provide services, rely on large-scale cloud computing processing capacity, standard operating procedures, flexible business coverage, accurate link control, intelligent decision-making support and in-depth information sharing to complete the logistics industry needs of the information requirements.

5, China's Construction industry safety monitoring System automation and information level is generally low, cloud computing's high scalability, high reliability, high flexibility and other 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 cloud computing, sensing network, computer image processing, pattern recognition, artificial intelligence and automatic control and so on, using computer vision and video analysis method to analyze the video sequence of camera recording automatically, and realizes the safe production of construction project, environmental protection at construction site, field capacity environment, Operating conditions for remote real-time image monitoring and management.
