This is an interesting portrait of container-based production stacks, but I'm sure most companies aren't using containers.

This also doesn't mention anything about the application you're serving: HTTP servers, databases; nor does it mention the vehicle you use to push changes to your application (source control? ssh to host? ssh to each guest container, good heavens?), control distribution upgrades (how would you upgrade your kernel? how would you upgrade apache?), and so on.

What do other kinds of stacks that aren't on the "Container Bandwagon" look like? Just "ordinary" provisioning of virtual machines?

With so many problems, I don't think "Container" can be considered as equivalent to "Modern" quite yet.
