On the role of Gang Yun in promoting enterprise transformation

Since the onset of the global financial crisis, the 9374.html "> World economy is entering a period of slow recovery but fraught with uncertainty after the financial crisis. A distinctive feature of this period is that Western companies rely on traditional high borrowing to implement an extended, fast-growing model that is hard to come by, and that developing-country firms are struggling to develop in the form of high-energy and low labour costs. In this situation, from the national government, down to the enterprise, the decision makers are faced with how to adapt to the changing situation in the new era, the search for fresh growth point to survive, development, expansion of the subject. Based on the author's personal experience in the industry, this paper puts forward some thoughts on cloud computing, especially Gang Yun, which is helpful for the industry to discuss and make reference to the enterprise decision-makers.

Definition of cloud computing and Gang Yun

Cloud Computing is currently in the information technology industry, the most "popular" technology, but also in the IT industry has formed a child industry to take shape. After referring to the definition of cloud computing by 21 experts, including cloud computing, Wikipedia and IBM, we have sought to use concise, accurate language to cover both business and technical definitions of cloud computing:

From a technical standpoint, Cloud computing is a dynamic and scalable computing model that provides virtual resources as a service, and from a business perspective, cloud computing is a web-based, large-scale service delivery and consumption approach. The payment of the service is based on the "demand for use" system.

In this definition, "resources" are not limited to computer resources or business processes, such as financial reimbursement procedures, personnel management processes, etc., can be virtualized into a service, available on the network. The cloud services provided on the internet are called "public clouds", and the cloud services offered on the intranet are called "private clouds", while the "hybrid cloud" that provides cloud computing services on the Internet and intranet.

from the composition of cloud computing, it can be summed up in a simple "cloud service" word. Specifically, cloud computing can be divided into three parts: the first part is "end", that is, the client, that is, customer consumer service interface and terminal equipment. At present, most of this piece has been Microsoft, Google, Apple and other companies monopoly; the second part is the cloud services provided by service providers, which is currently a "decapitated" state, the Future of cloud computing innovation and development of the mass market; the third part is "cloud", the infrastructure that supports cloud computing, mainly high availability, Energy-efficient data centers (T3 or T4), including computer equipment, storage devices, communications equipment, and cloud computing management platforms. In the past few years, Europe and the United States have launched large-scale data center transformation, upgrading or new to achieve improved data center energy efficiency, reduce carbon emissions and improve the use of computing resourcesRate。 This has laid a good foundation for the development of cloud computing in Europe and the United States. At present, the construction of data center is starting in China, and some leading enterprises have built advanced data center of T3 or T4 level. IDC forecasts this year that China's data center services market will remain double-digit growth over the next 5 years.

Cloud Computing has its unique advantages and disadvantages over traditional computing, compared to the advantages and disadvantages of traditional computing. The advantages are mainly embodied in three aspects. One is to improve the utilization of computing resources. Not only can improve the utilization of hardware resources, also can improve the utilization of software resources. Multi-tenant Support (multi-tenancy) means that the same software application can be used by a number of enterprises, because cloud computing provides a logically isolated environment in which software applications used by each enterprise are unaffected by others. The second is to greatly improve the efficiency of the operation, while increasing the availability and fault tolerance. The third is to improve the efficiency of information system management. Cloud Computing provides automated service management and automatic loading and unloading services without the need to manually install and configure software as in the past.

Of course, there are pros and cons to anything new, and cloud computing is a disadvantage because of its virtual and parallel environments, making it difficult for users to track which node a particular computing task is executing on. In addition, the parallel advantages of cloud computing will be difficult to use in computing tasks that involve too much access to unshared resources or the judgment and branching of complex business logic. The last one is that cloud computing provides a virtual and concurrent environment, as well as automated service management, which requires a certain cost of resources. If not for a large-scale computing environment, these costs will outweigh the gains.

Of course, we analyze these advantages based on current cloud technology features. Cloud computing is also evolving, there will undoubtedly be more advantages in the future, and some disadvantages will be improved.
