蒂姆Siglin: When we talk about live, large-scale events, how do you prepare for those?

Brenton咳嗽: 嗯，这很有趣. 我们确实举办过一些大型活动. What we see is that preparation is absolutely paramount. If you're going to be going to a global audience and doing a large-scale sporting event, you've got to be 200% sure everything's going to work. So you need multi-CDN, and you need all the switching to work--don't use simple DNS switching. You've got to have sophisticated tools that actually can do things very quickly, 做决定, 利用现有的数据. One of the things that I've seen that's helping these big events be successful is making sure you've got lots of redundancy. 这就是为什么你有多cdn.

但它不仅仅是多cdn. 你必须有多条路径. 你必须有多个编码器, multiple paths through your origin shield all the way through you've got to have redundancy and you've got to monitor all of that. 但我认为在最重大的事件上, 最重要的两件事是, 第一个, 确保你真的测试过了. So if you're going to do a big Super Bowl or something like that, 你必须测试每一个场景. 实际上，你必须强迫一切都失败, to make sure that all of those scenarios we play are actually going to work. And you have to have the runbooks effectively to make serious operational activity.

The other thing that I've noticed more recently--some of the bigger companies are really taking seriously, because there's huge teams working on this and there's lots of vendors associated with it--is having very clearly laid out decision-making pathways. 在情形A中, 做决定的人是谁, “我们要把CDN删掉, 或者我们要这样做, 或者我们要改变它"或者其他什么. 当你举办大型体育赛事时, 你没有时间去想, “你觉得呢?? 你觉得呢?" Someone has got to be designated as the right person to make that decision.

I've found the ones where those sort of things are all prepared beforehand--that's what makes those events successful.

Is Multi-CDN Always the Answer for Five-Nines Uptime Streaming at Scale?

Taking a multi-CDN approach would seem to be a no-brainer for delivering large-scale streams to global audiences and maximizing uptime in the face of bursts, 意外的区域需求, and other impediments to a smoothly delivered high-stakes stream. 但DAZN的鲍勃·汉内特表示，情况并非总是如此, and a multi-CDN approach can actually introduce inefficiencies, in this discussion with CDN Alliance Chairman Mark de Jong at 流媒体 Connect 2023.
