Hi Jaime, I now have 4 production web2py apps that have been up and running on Lambda for many months now with no issues. It is easily maintainable and I can update/deploy with a single command line: zappa update
As for the databases, the DB doesn't have to be AWS. You can connect to any database you like with the URL in the connection string in the DAL constructor. Out of my 4 apps: 2 of them use MySQL RDS on AWS 1 of them uses MySQL Aurora on AWS 1 connects to a non-AWS in-house database on a dedicated server at a non-AWS data center. The only issue with lambda, and it is a minor one, is that each idle lambda instance will go to sleep after about 10 minutes and then take about 10 seconds to spin up again. So when your number of concurrent requests hits a new high water mark for the last 10 minutes or so, that last user will have to wait up to 10 seconds for his request to get served. This is easily fixed by using https://www.lambdawarmer.com -- It's cheap and I use this to keep 8 instances warm. Zappa out of the box only lets you keep 1 instance warm.
