This spring, all areas of society have been affected by the epidemic to varying degrees. In all fields, education is undoubtedly the top priority, and it is also one of the issues that people from all walks of life are most concerned about when fighting the epidemic.

Since February 4th, the leading group of the Ministry of Education in response to COVID-19 's epidemic situation has successively issued three documents, such as "guidance on doing a good job in online teaching organization and management in ordinary colleges and universities during epidemic prevention and control", "notice on using informationization to support education and teaching work during epidemic prevention and control" and "notice on doing a good job of teachers' work during epidemic prevention and control". All of them put forward specific requirements and guidance for online education.

By February 12, the Ministry of Education and the Ministry of Industry and Information Technology jointly issued the Circular on work arrangements for the suspension of classes without suspension during the postponement of the opening of primary and secondary schools, further clarifying the basic strategy of actively adopting online education throughout the country during the special period of the epidemic, and proposed to open the national primary and secondary school network cloud platform and China Education Television air classes to provide high-quality teaching resources.

For a time, "suspension of classes without suspension of school" has become the first key word in the educational battlefield in the war against epidemic.

On February 17, the "National Primary and Secondary School Network Cloud platform" was officially launched. This means that at the critical moment of fighting the epidemic, the Ministry of Education organized the superior teachers of various provinces and cities to come forward, and the "national team" was officially launched! According to People's Daily, the platform received more than 8 million hits on its first day. Users cover 31 provinces (autonomous regions and municipalities) across the country. There are also users from 47 countries and regions around the world. About 85% of visitors use mobile devices such as mobile phones and tablets.

In just a few days, the "national primary and secondary school network cloud platform" has changed from a strategy to a reality, and behind it is a technological race between China's top technology companies, represented by Baidu, and time and the epidemic.

Behind the banner of hard-core technology, Chinese society is launching a grand technological experiment and social exploration in the face of Internet + 's new model of video, cloud computing and education.

From the hot line of the cloud computing industry, we seem to be able to see the further future of China's education industry.

Under "suspension of classes without suspension": problems exposed in online courses

The spread of the COVID-19 epidemic coincided with the end of the winter vacation and the beginning of the school year in various regions. This also makes how to deal with the relationship between epidemic prevention and control and the beginning of school, the first time to become a node of common concern of the community.

With the clear instructions of the Ministry of Education and the active exploration of various regions and schools, online teaching and online learning has become the main solution to this problem. However, with the independent development of online teaching in various places, some corresponding industry problems are also exposed.

As China's online live broadcast and online education industry has not ushered in such a large-scale and simultaneous wave of users, various platforms are not fully prepared for emergencies, resulting in large-scale online education on existing platforms, resulting in a series of problems:

1. The cloud service support ability of the online education platform is poor, and the platform is easy to collapse.

The news of the collapse of an online course platform went viral on Weibo on Feb. 17. After that, a large number of online course platforms and online office platforms have crashed due to excessive traffic. Because these products did not presuppose the peak demand of user flow in the special period of the epidemic at the beginning of the design, the platform collapsed one after another, which affected the progress of teaching and research in many areas and schools.

2. Teachers, students and the platform do not adapt to each other, resulting in the "non-suspension" experience is not so good.

It is understood that at present, online education is carried out in different places, and even the types of platforms used are different. Online office platform, online course platform and online live broadcast platform may all become the chosen objects of the school. But there are many features and product experiences that are not designed for online education for large-scale students. This makes it difficult for teachers and students to adapt to the operation of the platform, and many educational means and experiences can not be completed in the online scene.

3. The problem of network coverage in remote and poor signal areas.

Another problem of centralized online teaching is that the network conditions in rural areas, towns and counties, urban villages and other areas are not excellent, and there are a large number of problems in signal and data transmission. In a certain place, there is even a phenomenon of children in the village collectively scraping the net outside the village, which is very distressing.

The exposure of the three major problems shows that the key way to realize "suspension of classes and non-stop learning" is to ensure a high-standard and integrated online education platform and the concentration of curriculum resources, as well as strong technical support capability. be able to provide technical protection for the integrated national online education platform.

And the "national primary and secondary school network cloud platform" in a very short time, completed this can be called the "online infrastructure demon" of the Chinese miracle.

The national team shot in the hot line, Baidu hard core guard flag.

The national primary and secondary school network cloud platform, which was launched on February 17, is an important online education platform launched by the Ministry of Education to integrate the high-quality teaching resources of the country, relevant provinces and cities and schools. Through this platform, students of school age across the country can choose to use high-quality educational resources free of charge. The platform includes epidemic prevention knowledge, red education resources, special education resources, and curriculum resources of major subjects from primary school to senior high school.

(the picture shows the history course offered on the national primary and secondary school network cloud platform.)

At a special moment, on-line such a special platform, it is obvious that the biggest test is whether the carrying capacity of the platform can withstand the test of national users. The national primary and secondary school network cloud platform will meet the needs of nearly 180 million primary and secondary school students and 10 million teachers across the country, and it needs to promise that 50 million students will not get stuck online, coupled with the special requirements of getting online quickly. The technical support challenges of this platform can be imagined.

To this end, the Ministry of Industry and Information Technology has mobilized the "top team" of domestic science and technology companies to participate in the construction. With Baidu as the primary support force, together with Ali, China Telecom, China Mobile, China Unicom, Netcom, Huawei and other enterprises to provide comprehensive technical support, coordinated 7000 cloud hosts and 90T bandwidth, realizing the Chinese miracle of speed and quality insurance. And Baidu Smart Cloud is the main force of the national primary and secondary school network cloud platform, in the basic cloud resources, complete solutions, comprehensive technical support and other aspects of comprehensive "flag" online education national team.

The technical force behind "no school suspension" not only shows the responsibility of Chinese technology companies at a special moment, but also depicts the infinite possibilities of cloud + online video + education scenarios in the future.

From the Anti-epidemic Battlefield to the era of Cloud Education: the Technical password of Baidu Intelligent Cloud

The power of technology is often like this, the daily industry accumulates a long stream of water, and the power of the mountain collapse and tsunami burst out in an instant. Without the gradual improvement and maturity of China's cloud service market, Baidu Intelligent Cloud has accumulated the comprehensive capabilities of video solutions, cloud and AI, so the "China Project" built on the cloud is unimaginable.

Let us regard a technology company as a team, and we can find that the technical flag campaign of "suspension of classes and non-stop learning" is composed of a variety of technology, organization, and comprehensive service capabilities. In mobilizing forces to complete the task of platform construction, we can see three fulcrums that constitute the "technical password" behind Baidu's intelligent cloud.

First of all, efficient organization is the premise of everything.

During the epidemic, it is no exaggeration to protect the online learning needs of primary and secondary school students across the country. To this end, Baidu set up a major special security team as soon as it received the demand. Under the overnight work of more than a dozen industry and research teams, it took only seven days to complete a large number of basic cloud resources preparation and debugging work to ensure that the platform was officially launched on February 17.

Secondly, the advantage of cloud + AI+ video technology is the core competence to complete the challenge.

As mentioned above, the biggest challenge in the construction of the national primary and secondary school network cloud platform is how to make it easy for 180 million students to use it and 50 million users without downtime online. The key to this problem-solving ability is Baidu's leading cloud + AI capability, as well as intelligent video cloud solutions.

In order to ensure that the platform is "silky and smooth" to use, Baidu Smart Cloud provides a number of products and services for this project, including intelligent video cloud solution, object storage, cloud host, elastic public network IP, document service, content distribution network, security products and other products, so that the national primary and secondary school network cloud platform has the ability to store, process and distribute massive video / document resources.

Through Baidu Intelligent Cloud Video Cloud's intelligent ultra-clear transcoding service, the bandwidth consumption can be reduced by 30% in the case of clearer picture quality, so that students can also smoothly carry out online learning in areas with limited network conditions. At the same time, Baidu Smart Cloud CDN service also provides high-speed network access experience for students and teachers in all regions of the country, avoiding stutters, delays and other phenomena, and fully ensuring online learning channels for every student and teacher.

Behind a series of technical guarantees, Baidu Intelligent Cloud is the technology leader in the field of video and machine vision, and is building a new strategic highland in the cloud service market. In 2019, Baidu Smart Cloud has combined the advantages of cloud and AI technology with video processing capabilities to build video lifecycle specialized services, which can simplify the construction of complex video scenes, lower the threshold for video business entry, and ensure that cloud service users can quickly set up their own intelligent cloud platform and intelligent video business.

In November, Forrester released the "The Forrester New Wave: Computer Vision Public Cloud Platforms In China, Q4 2019" report, which shows that in the field of computer vision, Baidu Intelligent Cloud is at the top of the leader quadrant and leads the cloud service industry in an all-round way. With intelligent video and machine vision technology capabilities, Baidu Intelligent Cloud can provide the finest-grained image analysis and generation services, allowing video solutions to meet the needs of many vertical industries. At this critical moment of the epidemic, this ability has become the key card of the "national team" in the field of education, turning a challenge into a possibility.

Third, comprehensive service capacity is also very important.

In addition to organizational efficiency and technology leadership, Baidu Smart Cloud also comprehensively escorts the national primary and secondary school network cloud platform in terms of service, management, security and so on. For example, it provides a full set of cloud security solutions, integrates management methods and technical tools, and reinforces layer by layer from network access to host security. at the same time, the expert emergency response team is arranged to put forward plans for all kinds of information security risks that may arise.

The good news of the anti-epidemic battlefield continues to come, but this "forced upgrade" of China's online education industry will not end with the anti-epidemic. In this large-scale exploration of "suspension of classes and non-stop learning", teachers, students, parents, as well as relevant institutions and industrial organizations have seen many opportunities and possibilities. Online education can not only improve learning efficiency and provide an important supplement for school education, but also strengthen educational equity and provide a path for further exploration of basic education upgrading.

Under the iceberg of online education is the new industrial vitality of the integration of cloud computing, AI and video industry. The technological test in this epidemic is also a key to the future. Baidu's corporate role at a critical moment is also the best self-proof for the vast future of cloud + education.

"suspension of classes without suspension of school" is a far-reaching educational experiment completed by the whole Chinese society in a special period. It will play a key role in further improving education security and promoting education equity-as does Baidu's hard-core flag in the wave of cloud computing + AI, industry-wide video, and intelligence in the education industry.
