The Concept and Application of Cloud Computing
1. 1 Basic concepts of cloud computing
Cloud computing is the development of distributed computing, parallel computing and grid computing, or the commercial realization of these computer science concepts. It is a dynamic, easy-to-expand, virtual computing method that is usually realized through the Internet. Users don't need to have professional knowledge inside the cloud, know the details inside the cloud, or directly control the infrastructure.
The basic principle of cloud computing is that computing resources are distributed on a large number of computers on the network side, not on local computers or a single centralized remote server. Users can access different services provided by the cloud by accessing the Internet and using the programming interface provided by the cloud, cloud computing terminal software or browsers. Cloud? As the center of data storage and application services.
1.2 Overview of Cloud Computing Applications
At present, Microsoft, Oracle Bone Inscriptions, IBM, Sun, Intel and other IT giants are all facing the challenge of cloud computing, while Google relies on its search engine to catch up and stand out in this field. Google can compete with Microsoft and other software giants for several important objective reasons:
(1) data is the foundation of cloud computing.
Have a drink. Data? Clouds, there are computational clouds. Search engine is a technology to find information from massive data. With the increase of information and users, search engine technology can only support such a large-scale calculation by clustering more hardware and software. This is the embryonic form of cloud computing.
(2) Application is the catalyst for the popularization and development of cloud computing.
(3) The differences among Microsoft, Sun and Google.
The reason why Microsoft, Sun and IBM's cloud computing is limited to the application level is mainly because they have long relied on such a business model: customers realize client services by purchasing software media and installing them on a PC, and the more powerful the software, the higher the value. This makes the user experience process complicated, and it is not a simple software-as-a-service model. So their cloud computing and Google's cloud computing are different in concept and technology.
2. The impact of cloud computing on the Internet
2. Impact of1on technical development
(1) The end-to-end concept of the Internet is facing great challenges. At present, users are constantly upgrading their hardware and software to enjoy more Internet services. With the advent of the era of cloud computing, the client will become more and more simple, and almost all computing and storage resources are concentrated in the cloud. There is a serious inequality in resource allocation between cloud and client.
(2) A business-oriented computing model is proposed. Microsoft, IBM, Oracle Bone Inscriptions and other traditional software vendors generally make profits by selling software media. These softwares are installed on the user's PC. The more powerful the software is, the higher its value will be. In the era of cloud computing, users don't need to care about software maintenance and upgrade, which are all done by cloud computing service providers. Users can access the cloud through a browser to enjoy various services. Cloud computing service providers only charge for services.
(3) A storage mode based on distributed storage and unstructured data storage is proposed. At present, data are generally stored in private storage media of individuals and enterprises. Due to the influence of computer virus and other factors, its security is not high. If users transfer data to the cloud, these data can be professionally maintained and the security of data is greatly improved.
(4) A new fault-tolerant management mode and reliability concept are proposed. It is considered that a highly fault-tolerant and reliable system can be realized by using multiple low-end servers. In the case of unreliable hardware, combining multiple low-end servers into clusters through software technology can achieve the same functions as large servers, but the commercial cost is greatly reduced. This is also a remarkable feature of Google Cloud Computing.
(5) Propose a new business implementation mode combining with virtual technology. Virtual infrastructure provides an abstraction layer between computing, storage, network hardware and software running on IT, which simplifies the IT computing architecture, can control costs and improve response speed.
2.2 Impact on business development
(1) brings great development of Internet virtualization operation and promotes the further prosperity of Internet business. It can further lower the threshold of business innovation, further enhance the network capability and make users' use more flexible and diverse.
(2) It provides a good development opportunity for the information service industry and promotes the further transformation of telecom operators. On the one hand, telecommunication network will become a part of social infrastructure like water and electricity, providing high-speed network for cloud computing services. On the other hand, telecom operators will also compete with Internet service providers. Telecom operators will compete with Internet giants such as Google and Amazon. The advantage of telecom operators lies in their control of the underlying communication network. In addition, rich operating experience and good customer relationship also help telecom operators to occupy a place in the era of cloud computing.
(3) It has promoted the refinement and integration of the industrial chain and the emergence of new ISPs (such as resource leasing and virtual ISPs). Traditional IT vendors who rely on selling PC hardware or stand-alone software will be strongly impacted by cloud computing, because users no longer need to upgrade PC hardware or software endlessly as before. More service providers will transfer all kinds of services to the cloud computing platform based on cost considerations. Vendors with large cloud computing data centers will provide computing and storage resources for lease. With the sharp reduction of entry barriers, various emerging Internet services will spring up like mushrooms after rain.
(4) The emergence of the new concept of 4)XaaS has a great influence on the service concept.
2.3 Impact on industry supervision
With the emergence of cloud computing technology, the management and supervision of cloud computing related links in IT industry chains such as cloud computing service providers and virtual operator has become a new topic of Internet supervision.
(1) The emergence of cloud computing has completely broken the concept of region, and the contradiction between cross-regional storage of resources and local supervision will be intensified. This requires a global concept in the supervision of the Internet, and good communication and coordination between different regions in many aspects such as network resource storage, resource sharing and network security supervision.
(2) With the growth and maturity of the cloud computing market, it will also be accompanied by a new round of industry monopoly. In the process of research and promotion of cloud computing, several IT giants, such as Google, Microsoft, IBM and Amazon, have been in the leading position, and their huge investment in human and financial resources has ensured their great advantages in cloud computing technology. This advantage will surely make these IT giants monopolize the cloud computing market when cloud computing really starts to operate. How to restrain and guide the monopolistic behavior in the cloud computing market is a new topic of Internet supervision after cloud computing.
(3) Due to the difference between service provision mode and maintenance mode, the business operation mode on the Internet will inevitably change after cloud computing. How to redistribute various interests in the original business model of the Internet, coordinate the relationship between upstream and downstream enterprises in the value chain of the cloud computing industry, and introduce the operation and management measures of the Internet business after cloud computing as soon as possible, so as to promote the effective operation of the Internet industry chain after cloud computing, which will be the key issues to be solved urgently for Internet supervision after cloud computing.
3. The main problems of cloud computing
Although the cloud computing model has many advantages, there are also some problems, such as data privacy, security, software licensing, network transmission and so on.
? Data privacy: How to ensure the privacy of data stored in cloud service providers and not to be illegally used requires not only technical improvement, but also further improvement of laws.
? Data security: Some data are business secrets of enterprises, and the security of data is related to the survival and development of enterprises. The security problem of cloud computing data can not be solved, which will affect the application of cloud computing in enterprises.
? User habits: How to change user habits and make users adapt to networked software and hardware applications is a long-term and arduous challenge.
? Network transmission problem: cloud computing services depend on the network, and the current network speed is low and unstable, which makes the performance of cloud applications not high. The popularity of cloud computing depends on the development of network technology.
4. The service forms provided by cloud computing
According to the services provided by mainstream cloud computing service providers, cloud computing can be divided into:
Software-as-a-Service (SaaS): This kind of cloud computing mainly adopts multi-tenant architecture, and promotes a single application software to thousands of users through web browsers. This service is widely used in human resource management software.
Network services of cloud computing: Network services are closely related to SaaS, and network service providers provide APIs through the network to help developers expand their functions, rather than just providing mature application software.
Through the analysis of the current cloud computing business, we believe that the future cloud computing service providers will focus on providing services at three levels: software services in the cloud, development platforms in the cloud and information infrastructure in the cloud.
To sum up: we will wait and see about the future of cloud computing technology.
