The application fields of cloud computing mainly include the following three types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).
Infrastructure as a service (IaaS): IaaS (Infrastructure as a service), consumers can get services from perfect computer infrastructure through the Internet, which is called Infrastructure as a service. Internet-based services such as storage and database are part of IaaS.
Platform as a service (PAAs): PAAs is the abbreviation of Platform-as-a-Service, which means platform as a service. The business model of providing server platform as a service. The service provided by the program through the network is called SaaS(Software as a Service), and the corresponding server platform or development environment as a service in the era of cloud computing is called PaaS(Platform as a Service).
Software as a Service (SaaS): SaaS is short for Software as a Service. With the development of internet technology and the maturity of application software, it is a completely innovative software application mode that began to rise in the 2 1 century. It has similar meanings to "on-demand software", application service provider (ASP) and hosting software. It is a mode of providing software through the Internet, in which vendors uniformly deploy application software on their own servers. According to their actual needs, customers can order the required application software services from manufacturers through the Internet, pay the fees to the manufacturers according to the quantity and duration of the ordered services, and obtain the services provided by the manufacturers through the Internet.
Explain the application fields of "cloud computing"
Development trend of key application fields of cloud computing
At present, the application of cloud computing in major industries in China is only the tip of the iceberg. However, with the continuous maturity of localized cloud computing technology products and solutions, and the rapid popularization of cloud computing concepts, cloud computing will surely become the mainstream IT application mode of important industries in China in the future, laying a core foundation for information construction and IT operation and maintenance management of users in key industries. According to the author's in-depth analysis of the current situation of informatization construction in important industries in China and the demand for informatization application in the future, combined with a large number of practical application experiences of foreign cloud computing products, the future cloud computing will be mainly used in the following fields.
(1) medical field
Pharmaceutical enterprises and medical units have always been industry users with a high level of informatization in China. Driven by the "new medical reform" policy, pharmaceutical enterprises and medical units will optimize and upgrade their own information systems to meet the requirements of medical reform business adjustment. Under this influence, the centralized application mode of informatization with "cloud information platform" as the core will be born, gradually replacing the current application mode with decentralized system as the main body, thus improving the internal information enjoyment ability and medical information disclosure of pharmaceutical enterprises.
(2) Manufacturing field
With the advent of the "post-financial crisis era", the competition among manufacturing enterprises will become more and more fierce. While constantly innovating products and improving management, enterprises are also vigorously optimizing internal supply chains and integrating external supply chains, thus reducing operating costs and shortening product development and production cycles. In the future, cloud computing will be widely used in the supply chain information construction of manufacturing enterprises.
In particular, through the organic integration of various business systems, an enterprise cloud supply chain information platform is formed, which accelerates the process of "R&D- procurement-production-inventory-sales" information integration within enterprises, thus enhancing the competitive strength of manufacturing enterprises.
(3) Financial and energy fields
Financial and energy enterprises have always been the "leading" industry users in domestic information construction. In the next three years, the informatization construction of enterprises in Sinopec, PICC, Agricultural Bank of China and other industries will enter the stage of "IT resource integration". During this period, IT is necessary to use the "cloud computing" mode to build a physical integration platform based on IAAS, integrate various basic server applications, form a highly reusable and unified IT resource pool, and provide unified hardware resource services to the outside world. Therefore, cloud computing mode will become a key weapon for information integration of large enterprises such as finance and energy.
(4) the field of e-government
In the future, cloud computing will help organizations at all levels in China to build a "public service platform". At present, * * * organizations at all levels are actively building a "public service platform" and striving to create the image of "public service * * *". In the meantime, cloud computing technology is needed to build an efficient technology platform, including:
(5) the field of education and scientific research
In the future, cloud computing will provide an effective research and development platform for universities and scientific research units. At present, the application of cloud computing has been initially applied in Tsinghua University, Chinese Academy of Sciences and other units, and achieved good application results. In the future, cloud computing will be widely used in universities and scientific research fields in China. Colleges and universities will establish cloud computing platforms according to their own research fields and technical requirements, organically integrate the servers and storage resources of the original subordinate research institutes, provide efficient and reusable cloud computing platforms, and provide powerful computer resources for scientific research and teaching, thus greatly improving the efficiency of research and development.
(6) Telecommunications field
In foreign countries, large telecom companies such as Orange and O2 not only provide ISP network services to the public, but also provide IDC equipment rental and SAAS product application services to users in different industries as "cloud computing" service providers. These telecom enterprises have also effectively promoted the rapid development and growth of foreign public clouds through their innovative product value-added services. Therefore, in the future, domestic telecom enterprises will become one of the main beneficiaries of cloud computing industry, get a lot of income from all kinds of paid cloud service products, realize the profit growth of telecom enterprises, and develop and implement cloud products and services by analyzing the needs of users in different industries in China, and build their own brand cloud service system. ......

What applications does cloud computing have in e-commerce?
Most e-commerce enterprises are small and medium-sized enterprises, and the flexible submission service and charging mode of cloud computing is very popular. Small and medium-sized enterprises can flexibly expand IT resources according to the changes of their own business needs, and avoid the redundancy and waste of resources to the greatest extent.
Advantages of cloud computing
Solve the problem of processing massive data at the same time, and have enough computing power and storage capacity to deal with it.
It can collect network products and application services in various fields and integrate users' network needs such as information processing, online shopping, information and games in one stop.
The perfect combination of Internet, mobile communication, short-distance communication and other technologies.
What are the main applications of cloud computing?
In theory, where information is needed, there is cloud computing. At present, it is mainly distributed in education and health related to people's livelihood, e-government related to institutions, private cloud related to enterprises and e-commerce.
In which industries can cloud computing be applied?
There are many levels of cloud computing applications. In the future, cloud computing will be everywhere. At present, the Internet of Things, smart cities and big data are developing well. Specifically, there are * * *, Internet, e-commerce and video. Yi Yun Ministry of Information has these cases, which have been developed for several years. Please refer to professional advice.
What are the main applications of cloud computing?
Cloud computing refers to the delivery and usage mode of IT infrastructure.
Refers to obtaining the required resources through the network in an on-demand and easy-to-expand way;
And can be obtained at any time, used on demand, and paid for by use.
What is cloud computing technology? Where are they used?
What is cloud computing?
In fact, the cloud represents the Internet. Through the computing power of the network, instead of using the software you originally installed on your computer or replacing the action of storing data on your hard disk, you turn to the network to do all kinds of work and store files on the network. This is a huge virtual space. Through the network services we use, we store the data in the server on the network, browse the web pages of these services through the browser, and use the above interfaces to carry out various calculations and work.
Guess what? In fact, you are already in the clouds.
Web-based e-mail services, such as Hotmail or Yahoo, can be said to be the earliest popular form in cloud computing. If you use Facebook to interact with friends, Flickr to store photos, or Google Gmail to send emails, you are already storing your data in the cloud environment and using cloud-based technology, which is the magic behind news.
Yunchonglang
Just like you can see the sky wherever you are, you can connect to the cloud computing service you need anywhere you can access the network, even if you are not on your computer.
Walk into the clouds
The success of netbooks and the development of mobile networks (such as mobile phones with Internet access) make cloud computing more popular, and one computer per person is a good driving force for cloud computing. Netbooks and mobile phones are usually defined as low-performance computing devices, so they consume less power and are quite portable.
Netbooks may not be able to run bulky Photoshop software smoothly, or they may not be able to store a large number of music documents. But because of cloud computing, netbooks don't need these functions. All they need is a browser and an internet connection, so they can listen to a lot of music, process photos online or send emails to other contacts on the cloud.
So, if all you need is to type a document, you may need to include some basic formatting. You don't need the complete computing power of Microsoft Word software, you just need to log in to Google Online Docs to achieve similar results.
In cloud computing, the server doesn't care how powerful your computer is. Some colleagues use a PC to connect to Google Docs in the office and an Apple MacBook at home. At the same time, there are many other services that can be completed through your mobile phone or application software on iPhone and Android platforms.
Multi-person collaborative cloud computing
You can log on to any computer to use cloud services, and your friends or colleagues can also log on and work with you on the same document. Google Docs is just an office-type cloud computing service, which can operate collaboratively. Some services even allow people to use services in different parts of the world and work on the same documents at the same time.
Cloud computing may sound great, but it still has some hidden concerns that you must consider when using it. As Richard Stallman, a celebrity in the open source camp, pointed out, your information is in the hands of third-party vendors, and it is beyond your control.
Is it safe on the cloud?
The most likely problem is security. Few companies will want to steal your information and design websites, but it's best to study various websites and network services and find some reliable experts to recommend them, such as Lifehacker or your humble servant, technical madman.
Even if the service of a website is well-known and trustworthy, there may still be technical problems. This year, Google Docs leaked private data due to equipment failure, and Spotify, an online music streaming service, may become a target for hackers to steal user data.
cloud security
Fortunately, a little common sense and some simple and correct computer operation exercises can minimize the impact of such security errors and avoid putting your confidential information in the cloud. If there is, for example, when using online banking, avoid doing it on public computers in Internet cafes, schools or libraries, and don't give your real contact information too casually. ......
Application fields of cloud computing technology
Cloud computing is applied to industry, medical care, catering, architecture, * * *, and so on. Now, we use cloud services all the time, but through these clouds, how do I know which corner of the mountain it is? . Baidu and Google use cloud storage and interactive services to have a lot of data. It covers platforms and services, infrastructure services, software and application services.
