This is truly amazing and has so much baked in I find myself wanting to use it. However most apps my team and I work on require some form of persistence - uploads, log ins, API rate limits, etc. These scenarios don't fit well with the serverless world. It is technically possible to offset most of this to S3, a hosted NoSQL and perhaps even a service for dealing with a images/thumbnails. By that time your monthly bill is in the three digits, though. For a big web shop this is fine but your average freelancer with multiple smaller and finite-resource projects it's something to consider carefully.
