Containers also make performance tuning and optimization a lot harder, and increase resource consumption by a far greater degree than people are willing to admit. On a by-container basis it's not a lot, a few hundred megabytes here and there, but it builds up very rapidly.

This is compounded by containerizing making the ecosystem more complex, which creates a demand for additional containers to manage and monitor all the containers.

I freed up like 20 Gb of RAM by getting rid of everything container-related on my search engine server and switching to running everything on bare-metal debian.

Containers of course add some overhead, however it is negligible in modern world.

I honestly don't know what you have to do to get 20 gigs of overhead with containers, dozens of full ubuntu containers with dev packages and stuff?

I feel the people most enthusiastically trying to convince you of this are the infrastructure providers who also coincidentally bill you for every megabyte you use.

Maybe 5 Gb from the containers alone, they were pretty slim containers, but a few dozen of them in total; but I ran microk8s which was a handful of gigabytes, I could also get rid of kibana and grafana, which was a bunch more.

They don't though? Cloud providers sell VM tiers, not individual megabites, and even then on Linux there is barely any overhead for anything, but memory, and memory one is, again, if you optimize it far enough is negligible.

My k3s with a dozen of pods fits in couple gigs.
