(spoiler alert: you can’t)
Breaking the Internet. It’s as old as the Internet itself. The first culprit: web pages. Cacheable content. The band aid: CDN. It worked well, and it wasn’t done. The next major culprit: video of the Netflix variety. Same cacheable content, bigger scale. CDN and done, again.
It’s happening once more. Today, it’s all about real-time. And CDN won’t be coming to the rescue. We are talking live, interactive video. Major applications like interactive eSports (Twitch and Mixer), or collaboration (Zoom and FaceTime). You can’t cache me now, because time machines aren’t real like hoverboards. Network issues — jitter and latency variation in particular — can really wreck the user experience.
CDNs can’t solve this problem. Only a better network can. And there are essentially only two ways of delivering this.
