I disagree with the management simplicity argument. I’ve tried both and personally prefer VMs over metal for non-cloud container deployments. VMs (e.g. via vsphere on top of the metal) allow you to: * Have more kernels (lowers container to container interference) * Allocate iops to things * Choose whether you want to use the vm layer (vmotion/drs) to achieve uptime in the face of hardware failure or downtime - if you are metal only you have to cluster everything. * Trial new stuff (different base OS or scheduler) much more easily * Get networking the way you want it without configuring switches or moving cables all the time. BTW the terraform vsphere provider + govc makes managing vsphere with no pointy clicky pretty easy these days.
