Standing on the shoulders of giants, Netflix engineers didn't have blog posts from other companies on how to handle the scale they started facing. Facebook didn't have blog posts to reference when they scaled to 1B users. They pay for talent that have built systems that had not been built before and they have seen a return on it so they continue to do it.

Hulu was around before netflix

Sure? "After an early beta test in Oct. of that year, Hulu was made available to the public on March 12, 2008—a year after Netflix launched its own streaming service."

Hulu was never Netflix scale. YouTube is a better example.

[jedberg]

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]

I 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.

There was a Google organised hackathon on this topic. Given a set of resources, locations, and (estimated) popularity, Optimise for video load time by determining what should be moved to the cache when and where.

[skyde]

did anything from the hackathon turn out to be used?

[birdyrooster]

Not even close. YouTube has orders of magnitude more content and vastly more users. Google Global Cache was the inspiration for Open Connect.

yeah and have you see the awful performance of Hulu? its basically unusable. poster child for under investing in the streaming platform.

[paxys]

Huh? Netflix predates Hulu by over a decade.
