Good article though I would disagree about AWS Reserved Instances. Though they are way more complicated, they can give 40%+ discount and in many use cases you can run quite a lot of them.

Isn't it true that those require a 1-yr or 3-yr commitment? You can't move a reserved instance to another region. IIRC, its tied both to a region and AZ. OTOH, spot instances can be cheaper but then you should be prepared for those to vanish anytime.

  As of September 2016, you can buy a convertible reservation that allows you to move a reserved instance to a different AZ within a region. Your greater point still stands but I just wanted to correct one piece of it.

    Thanks for the update. The change appears to be relatively recent, and I'm not surprised being unaware :)
