I see people having a small 8 gigs and 4 core system and trying to split that with something like proxmox into multiple VMs. I think that’s not the best way to utilise the resources.
As many services are mostly in ideal mode so in case something is running it should be possible to use the complete power of the machine.
My opinion is using docker and compose to manage things on the whole hardware level for smaller homelab.
Only split VMs for something critical, even decide on that if it’s required.
Do you agree?
It all comes down to “what are you trying to do.”
Not everyone runs applications, so docker is not the answer to everything.
But if you only have 8Gb of RAM and are trying to run VMs then I’d advise you to go buy more RAM.
