Over the years, my country has attached great importance to the development of a new generation of information industry. The State Council issued the "Opinions on the Promoting the Development of Cloud Computing Innovation and Development and Cultivation Information Industry", the Ministry of Industry and Information Technology formulated cloud computing "13th Five-Year Plan", the Ministry of Science and Technology deployment national key research and development plan "cloud computing and big data" key special items, Development provides top design.
In fact, cloud computing is not a new concept, and its development history can be traced back to the formal proposal of 1956 virtualization technology. my country’s cloud computing and development is generally experienced three stages: 2010 is the preparation stage; 2011 to 2013 is a steady growth phase; Currently, cloud computing is transforming from new states into a regular manner, and is integrated with traditional industries.
According to the statistics of China Turnover Institute, the global cloud computing market is generally stable and growing, and the average growth rate in the market is about 20% in the next few years. It is estimated that by 2022, the global market size will exceed $ 270 billion, and my country’s cloud computing market will reach 17.31 billion yuan.
What kind of technology is the four major technologies to support cloud calculations? With high speed network, cloud computing connects a large number of independent computing units to provide scalable high performance computing power.
Its main feature is: resource virtualization, service on demand, generalization, deployment can be expanded, use can be charged. Simply put, the user’s calculation needs do not have to be implemented on the local computer, but as long as the calculation requirements are handed over to "Cloud Platform", "Cloud Platform" decomposes the huge amount of data into countless small tasks, distributes to many servers, and finally summarizes The calculation results are returned to the user. For an alteration, eat fish, you don’t have to ship, knot, go out of the sea, cooking, just need to order under the hotel, the hotel will go to the restaurant on time, this hotel will serve many customers at the same time. As users have more and more, the program is increasingly complex, and the requirements for computing power and security are getting higher and higher. Under the continuous improvement of demand, cloud computing technology is constantly upgrading, and application is getting more popular.
Cloud computing is mainly composed of four rigid districts such as data access processing, resource allocation, system security and service flexible applications.
These four major functional areas are supported by four major technologies: data center technology, software definition technology, cloud safety technology, mobile cloud computing technology. The data center is mainly hardware devices, responsible for organizing, processing, storage, transmission, etc.
According to the role played in the data center, it can be specifically divided into platform providers, service providers, and end users.
Among them, the platform provider provides software and hardware infrastructure for the data center (such as Alibaba Cloud); service providers provide applications such as websites and mobile apps; end users are the main objects of data center services, our common social communication software Such as WeChat, Weibo users are end users.
The core technology is a software-defined "resource virtualization" and "Programmable functions", the main task is to hardware "school work", and is responsible for organizing, coordinating and co-ordination.
It’s like there is a very good server performance, resource virtualization is achieved by "cloned" to assume the work of several servers in order to protect the basic needs of cloud computing.
With these techniques, software-defined pool of computing resources can support unlimited expansion, to solve the storage problem of uneven distribution, improve network throughput cloud platform.
The data to the "cloud" to deal with, will not result in the disclosure? Cloud computing more popular, the more pressing issue of information security. The focus is on information security and privacy protection encryption, network security is the key to prevent unauthorized access and malicious code, the core of cloud security is the security of using shared technology. Specifically, the cloud security technology generally include data security, access control and authentication, shared technical issues, system security vulnerabilities, insider threats.
As the cloud security complex, changing, cloud service providers should assume more responsibility for security, ecological security continuously push forward the construction of cloud computing and improved. Over the past 10 years, I believe people have a common feeling: more and more smart phones, more and more ubiquitous. Many office in the past only on the computer, television, entertainment, can now be done by phone, and some more handy functions on the phone.
One important technical support behind this is that mobile cloud computing technology. In the four pillars of cloud computing technology, this technology from ordinary people recently: it cloud computing, storage benefits apply to the mobile terminal, which broke through the resource constraints of mobile end, improve the user experience. Escalating more "useful" With the rapid development of the Internet, the increasing volume of users, type of business one after another. During this period, like the "double 11" Shopping Festival so difficult to accurately estimate the typical traffic load conditions and technical requirements have occurred, cloud computing technology challenge to the existing system. In the Internet era of all things, how to provide users with a more flexible and convenient information service? How to provide a simpler, customizable, manageable technology architecture for the service bearer party? New issues, new demand after another, all in the promotion of cloud computing technologies iteration.
After years of development, cloud computing grasp what the "new skills"? Cutting-edge technology of cloud computing are mainly hybrid cloud technology, ultra-fusion technology, edge computing technology. Ultra fusion technology to solve the problems of the conventional storage capacity, performance and computing power does not match developed by.
Super Fusion architecture means that not only have the same set of unit device computing, networking, storage and other computing resources and technology, but also speed up the cache, deduplication, compression and other online data storage technologies. In layman’s terms, had to build a data center need to buy a separate group of servers, a group of switches, memory and a number of related software, now only buy with the structure of a group of ultra-fusion machine on it: be achieved through a network module of seamless scale, form a unified resource pool. Edge computing this new computing model can help solve the shortage center capacity, network latency is long, energy transmission, privacy and poor. For example, two lives: we often use video conferencing and cloud storage, that is, the edge computing technology products.
Today, video conferencing has many people working normal.
Video conferencing, voice delay, poor quality video, screen sharing, the freeze is not uncommon.
Widespread use of cloud storage (such as Baidu cloud), the situation can not be accessed even sometimes appear too slow. Edge computing technology can alleviate these problems. Widely applied well to earth only to realize the value of cloud computing technology. Currently, cloud computing is through the information industry market, deeper and deeper into our daily work and life.
Chief clouds, cloud finance, industry and the Internet cloud technology industry, we not only bring great convenience, but also inject vitality into my country’s economic development.
E-government cloud led by government departments, professional information technology enterprises. E-government cloud cloud computing technology, e-government systems management and services streamline, optimization, integration, while providing the infrastructure, support software, application services, information resources, operational security and information security cloud services to government departments. Financial clouds while ensuring the financial institutions of information security, regulatory compliance, data isolation requirements for financial firms dealing with unexpected business demands, rapid deployment of on-line business to achieve business innovation and reform to provide strong support.
We live in frequently used payment instruments, such as Alipay payment and micro-letters, is a typical financial cloud services. Industrial cloud over the Internet will be flexible, sharable resources available to manufacturers, according to user needs to provide quality, timely and low-cost services, and manufacturing needs and social resources, manufacturing high quality and efficient docking.
Industrial cloud also difficult for SMEs to provide their own separate development of cloud hosting rental service and intelligent office systems.
Compared to traditional cloud computing, industrial cloud can facilitate the sharing of resources and industrial docking of supply and demand and operational capabilities to provide application services for R & D, manufacturing, marketing services, business management and other aspects of manufacturing. Today, cloud computing has become an important industry people’s livelihood, and into the homes of ordinary people in a variety of application forms. Can be expected, with the layout of the "new infrastructure" the process of gradually deepening, cloud computing has great potential for the digital technology industry representatives, will be an important focus of our transformation of economic development, high-quality digital economy.
