I think that you want somebody who's unbiased to answer this from their perspective (I'm a PM for Azure DevOps, so I'm pretty biased). But I've built out Azure Pipelines for many platforms, including Ruby and RoR with a lot of success. Feel free to drop me an email (my HN username @microsoft.com) and I can point you to some pipelines.

Cool. The trick is, I don't want to "build out a pipeline", I just wanna write a handful of lines in a single config file and be up and going, which is what travis has given me.
But Azure is def on my list to check out!
Haha, yes, sorry for making it sound bigger than it is. If you just want to do some build & test validation, it should just be a single yaml file. Not identical to Travis but close. We even added some getting started documentation if you’re familiar with Travis. https://docs.microsoft.com/azure/devops/pipelines/migrate/fr...
(Yeah, I know, all these CI things are hypothetically platform agnostic, but then there's reality, different platforms-under-test have different sorts of problems which become priorities for the CI platform to smooth out and make just work, or don't).
