Are others seeing this in software companies? Or have I seen particularly expensive CI systems?
There are repos we've seen that are heavily sharded for testing and trigger ~50-200 separate jobs per commit, each taking a few minutes to run.
CI costs are only going to increase with each engineer putting out 10x code and autogenerated tests in the next few years.
aside: we're tackling this problem as a company. I've been considering putting out an analysis of this data from our customer set - your post might just trigger me to do it.
