After reading this article, I had a few dissenting thoughts, maybe someone will provide their perspective?
The article suggests not running critical workloads virtually based on a failure scenario of the hosting environment (such as ransomware on hypervisor).
That does allow using the ‘all your eggs in one basket’ phrase, so I agree that running at least one instance of a service physically could be justified, but threat actors will be trying to time execution of attacks against both if possible. Adding complexity works both ways here.
I don’t really agree with the comments about not patching however. The premise that the physical workload or instance would be patched or updated more than the virtual one seems unrelated. A hesitance to patch systems is more about up time vs downtime vs breaking vs risk in my opinion.
Is your organization running critical workloads virtual like anything else, combination physical and virtual, or combination of all previous plus cloud solutions (off prem)?
Most everything everywhere is virtual these days, even when the host hardware is single tenant. Companies running hosted applications on bare metal are rare. I run personal stuff that way because proxmox was too much hassle, but a more serious user would have just dealt with it.
