Help me to understand, then. If this stuff is being done on an autoscaling cluster, I can see it, but if you are just running everything on an always-on box for instance, it is less clear to me.

edit: Do you have an affiliation with the blog? I ask because you have submitted several articles from checkly in the past.

Hey Checkly founder here, we changed our infra quite a bit over the last ~1 year. Still, it's mostly ephemeral compute. We started actually on AWS Lambda. We are on a mix of AWS EC2 and EKS now, all autoscaled per region (we run 20+ of them).

It seems tiny, but in aggregate this will have an impact on our COGS. You are correct that if we had a fixed fleet of instances, the impact would have been not super interesting.

But still, for a couple of hours spent, this saves us quite some $1Ks per year.

Yes I work at Checkly, though I didn’t answer authoritatively since this one wasn’t written by me!
