That’s an incredibly ignorant and misleading statement. It’s sort of like saying a database isn’t valuable because 99.999% of requests hit the cache, and not the disk.
Everything was built on Amazon and video is largely hosted on S3. Yes, there’s a large CDN in the mix too. That doesn’t take away from the achievement.
Well, what do you think Netflix is doing to be AWS’s largest customer? Have you seen any of their presentations on YouTube from AWS reinvent? Where do you think they encode the videos? Handle sign ins, etc?
Using a company that bypasses Amazon for 99.999% of its traffic isn't exactly an Amazon success story.
