Agreed, moving more and more stuff to the build, lighting up an image should be nearly instant, so we can do auto-scala etc... so no more "pip install -r" when bringing up an image, that's now part of the build. But the landscape for tools to build that image, be it a docker image or an AMI, right now, is the same. I find myself "going back" to ansible but now using it to build images rather than change online VMs (could be any tool, I know ansible and it suits my way of thinking).
