How to secure the bare metal cloud

Bare metal isn't exactly a new technology concept, it was first applied to a hard drive more years ago than I care to mention. In terms of a bare metal environment then, we must think of any network where a virtual machine is installed directly on hardware rather than running within a host OS. The term has now started to gain traction within the cloud environment, where it refers to dedicated hardware servers in a co-location space that specifically do not run a hypervisor and so are not virtualised but are still delivered within a cloud-like service model. Most commonly these are implemented by way of complimenting a virtualised cloud service, although they can sometimes be seen as a complete substitute.
