Edit: please ignore this reply completely. Obviously I read "Container" where it clearly states "VM". Now I need to think over it again...
Edit2: maybe the VM is in sleep or hibernation mode, from the inside --> not really turned off but also not up-and-running, just waiting for a wake-up call.
It is 85 MILLION Bytes. How could that be considered "not much"? ;-)
Containers use directly parts of the host's operating system - especially the whole kernel.
This means an empty/basic Container does really not contain much data or many processes. This is one of the reasons Containers are preferred over VMs, which are much larger by design.
