I think there is a lot miss understanding here, to me DevOps is not just automation (we've had that for a long time, Perl, cron, cfengine etc).

It's much about applying the same processes you would apply in development to Ops. For example committing changes into version control and only using that, not live patching things, much like you wouldn't live edit a website.

Also being able to spin up new servers based on a config and not requiring manual config to get it going. Automation alone does not get rid of 'snowflake servers' http://martinfowler.com/bliki/SnowflakeServer.html

Also, it can be about letting developers get the exact same environment for development/testing at no additional time cost - which in turn makes it more like that code changes can go live without problems or delays.
