I have just moved the scenemodels database web frontend at https://scenery.flightgear.org/ to AWS Lambda backed by CloudFront CDN.
Our frontend has very little access rates which makes it a perfect candidate for running in a "function as a service" environment with the option to scale down to zero. This means, there will be no computing instance running where there is no traffic. No CPU cycles are wasted while waiting for traffic means: no power consumed, no CO2 emitted and best of all: no costs for idle machines on my monthly bill.
There /might/ be a little warmup time when loading the address into your browser. This happens, when AWS has removed all computing instances due to inactivity and now has to reload the containers first. Every subsequent call should be answered as fast as it can get. Warmup should no longer take than just a few seconds, usually they not even noticeable.
Those of you who add objects or models to the database, please let me know if something is broken.
Stay safe, everybody!
