I was seduced by BlueOcean and tried using Jenkins for CI, using Github and AWS ECS builders (which felt like a common enough use-case).

Unfortunately it ended up costing an astonishing amount of engineering time to get working and maintain, with builds frequently stalled or failing.

Since moving to CircleCI 2.0 enterprise (admittedly far from perfect) and Airflow, we have _dramatically_ reduced eng. time spent managing our job scheduling.

The core of our problem was how fragile and complex the Jenkins ecosystem seems to be: any change to the config or settings and it would easily burn a day of engineering, due to random bugs and hard to understand error messages. In the end, no one wanted to touch it!

I think there's a great project hidden somewhere here, but just getting the basic "everyday" stuff done with it can be a real PITA.
