Youtube is very different than Netflix from a technical problem perspective. They serve free videos to anyone around the world that are uploaded by users.
It's closer to a live streaming problem than pre-encoded video like Netflix.
Having worked at Netflix I can say that the YouTube problem is much more complex.
- why_only_15 4y agoI wonder what portion of Youtube's request traffic can be served with cache servers at the edge with a few hundred terabytes of storage. There's a very long tail but i would guess a significant portion of their traffic is the top ~10,000 videos at any given moment.

- skyde 4y agodid anything from the hackathon turn out to be used?
- spockz 4y agoI’m not sure as I don’t work at Google and didn’t see any follow up. Maybe some in the winning teams would know. I do think there is some temporal logic already present in Google’s algorithm which wasn’t part of the challenge.
