Namespaces and cgroups and LXC and the whole alphabet soup, the “Docker Industrial Complex” to borrow your inspired term, this stuff can make sense if you rack your own gear: you want one level of indirection.

As I’ve said many times, putting a container on a serverless on a Xen hypervisor so you can virtualize while you virtualize? I get why The Cloud wants this, but I haven’t the foggiest idea why people sit still for it.

As a public service announcement? If you’re paying three levels of markup to have three levels of virtual machine?

You’ve been had.

You're only virtualizing once. Serverless/FaaS is just a way to run a container, and a container is just a Linux process with some knobs to let different software coexist more easily. You're still just running VMs, same as you always were, but just have a new way of putting the software you want to run on them.
