It works with such high efficiency because we know how to place content in advance, and the catalog is relatively small. Trying to serve 800Gbps of YouTube content would be a nightmare.
- ilyt 4y agoI wonder how much of YT traffic is the "big" (say >200k viewers in a month) vs the small guys. But yeah, once your hot data size exceeds cache byebye efficiency
- adgjlsfhk1 4y agoOne hard part is that on the youtube side, most views occur within the first 48 hours or so and a good fraction occur within the first 6. With netflix, they have a catalogue of ~5000 videos and gets <200 new per month. Youtube has around 30k channels with more than 500k subscriptions, so that's somewhere around 30k videos per week.

- drewg123 4y agoIndeed. YT has a much different problem, which is to determine which video is going to go viral, and then transcode it into popular formats when it does. In comparison, we pre-transcode everything to exacting standards, so all our CDN has to do is serve is static files.
