Lambda has its places, but I've noticed devs consistently using it for things where it doesn't make any goddamn sense. Like processing messages from a Kafka consumer, the function is running 24/7. People think it's a container or something.
yes where I work there is an alert for when a lambda is not running. I have proposed wrapping the lambda code in a while() loop on a fargate many many times to save $thousands of dollars but I lack the political power to actually do it.
