I've felt the same way. Serverless is most appealing when you're starting out and have low traffic. It enabled us at ipdata.co to have the most global infrastructure possible with the lowest latencies at an insignificant cost.

At some point I believe when we're big enough we might switch to using servers in all the regions where we currently run APIG+Lambda.

The advantage of Serverless to me seems that it already forces you in a somewhat sane design and separation of concerns so all work out into the lambda functions should be easily translatable into a different architecture.

Yes, very much this. A lot of the effort was extremely in-depth planning for scalability with respect to both unbounded traffic growth/adoption and expanding the team. In fact I coded an initial prototype in about a month that could have run quite happily on a single instance and subsequently broken out into a typical LB/Autoscaling group/DB architecture without much trouble. Now we have about 7 core microservices which are independenty scalable and deployable, many of which we anticipate handing off to dedicated teams as we expand and hire.

Very smart. Good point.
