Rackspace OnMetal を利用している企業
OnMetal servers are single-tenant, bare-metal servers provisioned via the same OpenStack API as our cloud. They can be spun up as quickly as VMs to offer the agility of multi-tenant environments with the performance of single-tenant hardware. OnMetal servers are our own design and are engineered in a highly opinionated way. We’ve made them 100 percent solid-state with external cooling, leading to increased mean time between failures (MTBF). They are also incredibly large, so you’ll need fewer of them.
