Alibaba Cloud Multimedia Solution

Millions of hours of Olympic video storage and streaming capabilities

Background
The Olympic Games is one of the most watched events in the world, with over 3 billion of the world’s population catching at least a minute of the Games. In the past, the only way to catch up with the action was by watching replays on TV. Now, with the power of the Internet, we can watch videos on-demand, anywhere, and anytime. It is predicted that millions of hours of video are stored and shared among users online. To achieve storage of this scale, we need a solution that not only is capable of handling large amounts of data but also is easily expandable.
Solution Architecture
According to the type and quality of a video, the average size of an hour of video ranges from only a few hundred MBs to as much as 18 GBs. Alibaba Cloud Object Storage Service (OSS) is ideal for storing files of varying formats and sizes, such as video files. OSS can be used in conjunction with Network Attached Storage (NAS) to achieve massive storage capabilities with cloud storage. With cloud storage, the cost for storing massive amounts of multimedia files can be significantly reduced as compared with purchasing permanent memory devices. This setup is also easily scalable, capable of quick expansion based on actual needs. Additionally, Alibaba Cloud OSS ensures data reliability with its triplicate technology. When you store a file, OSS automatically creates three copies of the file across multiple data centers, ensuring disaster tolerance and high availability.
