• Competition Their paradigms

?? ?? Procedural Image Based Transactional
?? - State ignorant Gatekeeper bound Constrained audit trail Diminishing undo over time No faster than Manual Labor intensive scriping All or nothing Only good for provisioning No roalback No audit trail Storage hog Network hog Slower than transactional Wedded to hardware Full state aware Tracks changes made by any means Complete audit trail Fastest Possible Reduced storage Portable dynamic
