I think I might disagree that this isn't "real" architecture. All system architecture is about designing a system to meet the defined needs. This system is designed to hit the starting needs and has an already designed migration to the medium-term needs. That idea of "YMMV" is very much relevant here as every system has different needs. Some of those needs are minorly different, others are wildly different. Anyone on this thread that's discounting FaaS usage out of hand with statements like "just run a $20/month server" are demonstrating a lack of imagination. Would I use it as the primary server for a medium+ traffic site, almost certainly not. But there is a whole world of low-traffic services that are well suited to using a FaaS platform over a dedicated server.
