VMs have a ton of overhead compared to Docker. VMs replicate everything in the computer while Docker just uses the host for everything, except it sandboxes the apps.
In theory, VMs are far more secure since they’re almost entirely isolated from the host system (assuming you don’t have any of the host’s filesystems attached), they are also OS agnostic whereas Docker is limited to the OS it runs on.
