Bare metal cloud provides infrastructure as a service (IaaS) by allowing users to launch virtual machines on dedicated physical servers, similar to how Amazon EC2 allows launching VMs but with direct access to physical hardware rather than a virtualized environment. This improves performance for high performance computing tasks compared to traditional virtualized IaaS. The document discusses how a bare metal cloud manages VM images and the boot process using PXE to directly boot VMs on physical servers without hypervisors.
