Netflix uses Docker in production. While they don't use it for everything yet, they are transitioning to it. Netflix accounts for 37% of internet traffic or more in North America.
Maybe you had trouble, but I think that those that aren't using containers need to be aware that many are using them successfully. Use of containers vs. VMs/dedicated servers can also result in reduced energy usage and can be less expensive.
I think people get hung up on what containers aren't and where they fail, rather than where they exceed.
But also be aware, that the traffic Netflix serves out of those containers is way less then 0.01% of the internet traffic in North America. The container cloud is their management engine.
The CDN that is actually pushing the traffic runs FreeBSD and would be using, if anything, jails.
