Interesting, never thought about applying idempotency to the more traditional programming areas like web dev, although I would like to think I develop my apps like this even without thinking about it in terms of idempotency. For those who might not be in the know, this is a crucial concept for IaC through tools like Puppet/Salt/Ansible etc, as it allows you to think/program infrastructure configuration as a state rather than scripting everything and having to take account of all the minute states that may exist on a legacy or well entrenched system.
