This. Containers are not ready for production, except for fault-tolerant/distributed payloads. You can't even live migrate them to another host, and CRIU is nowhere near production ready (assuming it ever will be).

Everything else? VMs it is. The overhead is so low nowadays that it's totally irrelevant for the vast majority of use cases.

Sorry everyone's downvoted you, despite that you're correct.

I do Devops, and Docker provides very little benefit in production (unless you're an org with your own non-cloud computing resources, where you're going to orchestrate with something like Kubernetes; even then, there's dissent in the ranks between that project and Docker).
