This document discusses several methods for deploying Linux servers at scale, including using PXE boot, Kickstart files, Cobbler, Foreman, and Puppet Razor. PXE boot uses TFTP, DHCP, and optionally HTTP and DNS to boot servers over the network. Kickstart files allow for unattended operating system installation and configuration. Cobbler automates Linux installation tasks. Foreman is a lifecycle management tool. Puppet Razor can discover, deploy, and manage both physical and virtual servers through automated provisioning policies.
