Baremetal hypervisors are physical servers that reside directly on the hardware without the virtualization layer. Baremetal hypervisors are hosted on dedicated baremetal hypervisors, deployed for a single user. Utilization of baremetal servers allows to locate customer's servers on a single piece of hardware. Use of baremetal servers in the cloud makes hardware resource utilization more efficient.
The advantages of baremetal servers:
- full access to the entire server
- tight security
Baremetal servers are hosted on Xen CloudBoot hypervisors, that can be then organized into zones to create different tiers of service - for example, by setting up different zones for baremetal servers, with limits and prices specified per zone. Baremetal hypervisor zones can also be used to create private clouds for specific users.
