I'm not a rep for the company or anything, I just discovered this through Product Hunt but the GSV Labs Passport is a program where you pay $600/yr and get $100,000 in AWS credits plus a whole bunch of other credits to stuff like Watson, Segment etc but for the AWS alone it's worth the sign up. I wish I knew about this years ago solely for the database savings. Figured this was a good group to put this in front of.
