> If I want my Supermicro/Quanta/Dell to boot from an image in a similar fashion I have to build the image, I have to host the image, I have to make it available on the network, I have to configure DHCP, I have to configure the BMC (and Redfish is probably not implemented quite right, lets be honest here), then I can boot from it.

But do you need to boot a custom image?

37signal's move off of cloud revolved around the idea of shoving everything into containers and deploying the containers using something like a cross between docker-compose and capistrano. The host OS barely matters at this point.

A scenario like yours is more the outlier than the norm, at least from my experience.
