Amazon does not have a 'baremetal' instance type. OpenStack 'can', but in practice the baremetal nova driver[0] has many issues, and the newer OpenStack Ironic Project[1] is not yet ready for production workloads. Additionally, both baremetal and OpenStack Ironic have a focus on 'triple-O', or OpenStack on OpenStack[2] use cases -- that is using these projects to bootstrap an 'undercloud', for the hardware to be used by a higher level virtualized cloud.

Fair enough. I was totally convinced that Amazon had baremetal instances available, but now I cannot find anything, so that could probably be a figment of my imagination.

  All of Amazon's EC2 compute instances are run on top of Xen; there is an interesting Reddit AMA post with a lot of detail: http://www.reddit.com/r/IAmA/comments/1e5o4p/iaman_exaws_engineer_ask_me_anything_about_the/ http://www.reddit.com/r/IAmA/comments/1e5o4p/iaman_exaws_eng...

    That is a very interesting thread, thanks. I think I was confusing dedicated tenancy with baremetal. Dedicated tenancy of course still runs on Xen.

  I believe at one point the GPU instances were being given direct hardware access to the GPU as virtualized GPUs weren't yet a thing. So the GPU part was sort of baremetal I guess.

    GPU instances are still Xen VMs, not bare metal.

> Additionally, both baremetal and OpenStack Ironic have a focus on 'triple-O', or OpenStack on OpenStack[2] use cases Well, I'm sure they have issues but what gave you the impression they are focused on TripleO use cases? As a TripleO dev I just use them. Compared to more 'standalone' softwares like MAAS, these tools are integrated already into OpenStack, allowing you to deploy images on either virtual instances or baremetal without adding more software layers in charge of the images hosting, authentication, dhcp management and what not.
