But is there a way that Netflix might have learned from all of Youtube's past mistakes? The only reasonable way to scale something like this up is probably to... scale it up. Sure, there are probably some generic lessons, but I bet that the pain points in Netflix's architecture (historically grown over more than a decade and optimized towards highly cacheable content) are very different from Youtube, which has ramped up live content gradually over as many years.
