New Oriental Education and Technology Group uses function computing to achieve computational flexibility

Through Alibaba Cloud function computing, New Oriental Education Technology Group successfully realized computing flexibility, carried the business peak of live video transcoding and screen recording, and effectively responded to large-scale sudden online traffic, greatly reducing operation and maintenance costs.

Customer introduction

New Oriental Education Technology Group is positioned as a comprehensive education group with students' overall growth as the core and science and technology as the driving force. New Oriental Education and Technology Group is developed from Beijing New Oriental School, which was established in 1993. Starting from the field of education, after 30 years of innovative development, the Group's business now covers three major areas: education services, life services, and cultural and tourism services. In the field of education services, New Oriental has built a comprehensive education service platform with all-round growth as the core and science and technology as the driving force, and built a quality education system and product system for primary and secondary students; Learning system and consulting system for people studying abroad; Various examination training and career development training systems for college students; Software and hardware development system for smart education.

Business challenges

The cloud classroom system of New Oriental online education business supports all online education scenarios of New Oriental, such as live video, transcoding, and on-demand. With the increase of business volume, because the live broadcast transcription and video transcoding task processing platform has obvious peaks and troughs, the low resource utilization rate of the self built machine room has become the core pain point of the business.

Live broadcast+recording is the main course delivery mode promoted by New Oriental. New Oriental began to connect with the online education business of college students, and put forward higher requirements for the quality of recording and broadcasting courses. The team began to consider using server side recording to solve the problem. The two core points of server recording are live recording and video standardization production. This business model makes it difficult to accurately predict the business volume. Therefore, the key technical task of New Oriental is to achieve computing flexibility.

Alibaba Cloud solutions
Recording and broadcasting transcoding usage function calculation

New Oriental uses Alibaba Cloud functions to calculate FC in the video broadcast transcoding scenario. The core demand of video recording and broadcasting transcoding is to transcode the live stream in real time, save it in a standard video format, and facilitate subsequent processing. After the teacher enters the room and initiates the transcoding request, he can quickly start the function instance to transcode. After class, the transcoding task is ended, and the function instance can be released immediately after the temporary audio and video results are uploaded to cloud storage, without any waste of computing resources.

Cloud recording uses function calculation

Next, record the project in the cloud and try to use function calculation. Join the live broadcast room with the Chrome browser to record screenshots of the browser interface. The key to this solution is to flexibly provide browser instances. Use Alibaba Cloud functions to calculate and start the Linux container, and run the Chrome browser in the Linux container to provide an elastic browser instance.
