Some comments wrongly equate bare-metal with on-premise. Bare-metal servers can be rented out, collocated, or installed on-premise.

Also, when renting, the company takes care of hardware failures. Furthermore, as hard disk failures are the most common issue, you can have hot spares and opt to let damaged disks rot, instead of replacing them.

For example, in ZFS, you can mirror disks 1 and 2, while having 3 and 4 as hot spares, with the following command:

    zpool create pool mirror $d1 $d2 spare $d3 $d4

About the break even point:

Disregarding the security risks of multi-tenant cloud instances, bare-metal is more cost-effective once your cloud bill exceeds $3,000 per year, which is the cost of renting two bare-metal servers.
