Callum, not everything is a "useless fad" just because you don't like it. I understand that you think AWS lambda functions are "just an expensive con for morons", but for our batch processing use case they really do make a lot of sense.

Running some numbers to show they cost 10x more for a completely unrelated always-on service with a completely different request pattern is either naive, stupid, or malicious, and considering you're meant to be a principle architect, I'm really not sure what's worse 🤦‍♂️
