IaaS is a cloud computing model in which storage, compute, and networking resources are available on demand over the internet through an IaaS provider

BMaaS can be considered a subset of IaaS that refers specifically to the practice of providing access to dedicated servers free of any installed operating systems or virtualization ⁠infrastructure—bare-metal. The customer may be provided access to the physical server hardware either remotely or on-premises

Compared to the traditional cloud model, where multiple users (multi-tenancy) may reside on the same physical server within a cloud vendor’s data center, the bare metal server only has one customer on the server (a single tenant server)

Access is usually provisioned on-demand via a single contract or service level agreement (SLA).
