This leads to an interesting thought.  The trend (currently) is to migrate things like e-mail off-premise because (in theory) you no longer need to pay someone to manage your Exchange / sendmail / postfix / etc system and it's required hardware.  BUT with in some locales the increasing requirements of maintaining data privacy will potentially result in a return to on-premise, we control it all, e-mail.

I have to wonder, also, how many businesses are rushing to the "cloud" without really thinking about what they really expect from it.  Where I work, we're supposed to be migrating to "the cloud" and have some rather stringent requirements when it comes to both what can connect to our network (so no just spinning up some Azure SQL instances for me,) and what we are required to have monitoring those systems.  So far, our "cloud" looks like it's going to be nothing more than our current setup of virtual machines picked up and dropped into some other data center outside our facility.  Some day.  Eventually.  Of course, at the current "blistering" pace of our migration, I'll probably have moved on from this position before anything gets done (they've been talking about it since I started about 3-4yrs ago, and there's been no movement that I can see in the last couple years.)
