On the other side of the coin, a few months ago I was annoyed by getting a redshift alert one too many times during maintenance that I spent a couple of hours on a Saturday writing a ~20 line Lambda project that took the notifications from Redshift and posted them in a Slack channel.

I didn't have to worry about setting up automation for launching an ec2 instance, monitoring it, paying for it, or any of the complex trouble for what ended up being a single python function that cost abotu $0.10 per month to run.
