Very nice writeup! A nice, detailed read that was easy to understand.
It seems to focus more on raw infrastructure (EC2 vs GCE) instead of each company's PaaS offerings. Obviously AWS has the front runner lead here, but would be super curious in a comparison of RDS vs. Cloud Spanner for instance.
(pun unintentional, but then realized, and left in there)
Did you mean to say AWS Aurora vs Cloud Spanner? Because, I don't think you can compare RDS vs Cloud Spanner. RDS is a managed for the most of the famous RDBMS out in the market (except Aurora). Cloud Spanner is a google proprietary db running only on GC.
