@lonk That's a totally valid, effective way to do it. Probably the most instantaneous of all the things mentioned, since it seems speed/latency is a priority for you. Lambda's not that bad to write code for - if you get pretty advanced with it, you can really run nearly any language on the platform, though the officially supported Java, Go, PowerShell, Node.js, C#, Python, and Ruby are the easiest options. You've got a lot of choices there.
