We take a helicopter up a few thousand feet to suss out what cloud security is really about. What security problems does cloud fix?  What security problems does it introduce?  One hypothesis is that a lot of IT is unnecessarily 'custom', and so is the security with it.  The reality in the world is there is still a lot of on-premises IT, multi-cloud, and shadow IT today. Bill brings up the real issues of cloud resource garbage collection and the impacts of counters, and Greg shouts out 'object re-use!' and 'Y2K!' like a crazy person.
