Isn't the main variable impeding the % of bare metal container deployments scaling with automation in areas such as inter-container networking and visibility. Many years of "wrappers" around VMs in those areas - people, processes and software. A few years for similar to develop for a containerized world? Until then, we run containers on top of VMs for use cases at scale because (even if not efficient from other perspectives) we do get the wrappers (wrappers which do impact time, TCO, risk, etc)?
