Behind the World Cup live cloud computing

When Suarez bites, Beijing's giants feast scene compared with the fans in the town of Yunnan, who saw this funny scene earlier? The answer is "almost simultaneously." This year's CCTV World Cup live a lot of progress, in addition to television and the official website, but also through the mobile phone screen to watch live, and can do mobile phones even faster than the official website! Why CCTV5 wireless APP live faster than the official website? The answer is that it uses a cloud computing CDN acceleration technology. This technology can be the World Cup live streaming video data to the user nearest place for access without having to load from thousands of kilometers away from the data center. In order to create a live broadcast without delay, CCTV calls China's largest CDN network, CDN, to enjoy the same level of technical support with Taobao. Aliyun CDN more than 240 nodes at home and abroad, the total bandwidth of about 6000G. What does this data mean? 100 million users visiting Taobao at the same time need to quickly find the desired product among the 1 billion items and see different picture displays - this series of actions may take only 1 second. In the past, fans watched the World Cup live via television and often ten seconds faster than watching live broadcasts on the Internet. This year, for the first time, CCTV attempted to place the backend of mobile apps "CCTV5" and WeChat public numbers onto the Aliyun cloud computing platform and use cloud computing technologies such as CDN to create the fastest and the live broadcast of the World Cup with television. In addition, the "CCTV5" APP also introduces a "Team AB-specific perspective" by leveraging the elasticity of cloud computing resources. For example, when the England and Italy wars, the Italian fans through the APP, you can choose to view the match from the perspective of the Italian team, from the lounge to the game, focus on the team, rather than passively accept the same TV broadcast two teams keep switching non-stop . If there is a vote hacker fans, see Germany lost too terrible, start throwing chaos hair DDOS big move how to do? The frenzied Aliyun engineers even think this is CCTV. In the CDN network provided for CCTV, Alibaba Cloud deployed 40GB of attack protection on each node, which is equivalent to the simultaneous attack of 10 million hackers to simulate, and will not cause network delay and paralysis. World Cup battle is in full swing. Currently CCTV5APP more than 300 million views per day, the online population is also rising. July 14 night of the final, is expected to have millions of fans at the same time pouring into the APP watch live.
