RackN designed Digital Rebar from the ground up to rethink how we manage physical data center infrastructure.  While fully replace the functionality of past generation provisioning tools, a feature-by-feature comparison missed our innovation around simplicity, integration, workflow and composability.

Cobbler is one of the oldest and simplest PXE provisioning services.  For long time users, the Digital Rebar template system will be a straightforward mapping.  As an early system, Cobbler lacks the APIs, DHCP, integrations and security features baked into Digital Rebar.
