Absolutely agreed. As others have already pointed out, there is no underlying implication of preference to this kind of application architecture. Since we do run an actual DBaaS, one of our main internal goals in running these experiments was to specifically test our Global Routing Infrastructure, and construct a scenario that allowed us to help size specifically those components for capacity planning.

As long-time DBA's ourselves, we do as much as we can to educate and empower users to architect their applications wisely... but we still need to be prepared for the worst. As it turns out, Lambda was an easy way to accomplish that. :)
