Don’t Ever Change! Are Immutable Deployments Really Simpler, Faster, and Safer?
summary
Shows an implementable path from configure-in-place to build-then-deploy by using image-deploy and in-memory netboot (demo uses Digital Rebar and CentOS), claims about a 5x improvement over traditional netboot and a live demo that writes a disk image and boots a machine in about three minutes vs ~9. Emphasizes the create-destroy pattern, needs reliable DHCP/boot infrastructure, requires post-deploy initialization and care for stateful disks and rollback policies.
