Sometimes. But look at Netflix. $8.8 billion revenue in 2016 and a good third of Internet traffic and nearly every single server they have is in AWS. They had their own custom data centers and made the choice to migrate to somebody else's infrastructure. I'm pretty sure they're doing just fine with that decision.

That's a really good example. They talk a lot about AWS, and nearly every service they run is in AWS. If you don't pay close attention, you might think they're all-AWS. I expect that Netflix' AWS pricing reflects that perception.

The exception is serving films. If you watch a film, you receive bytes served by hardware built to Netflix' specification, running in leased space at a mixture of colos and ISPs. That's a really big exception. The third of internet traffic is that exception.

They don't use aws for cdn (i think level3 and many others) + they design custom server-cache which they put inside isps.

That's…not true. Netflix has a huge CDN[0] running their own custom-built servers that sits near customer endpoints.

I shudder to think of how much bandwidth they'd be paying to AWS if they didn't…
