    Ha, after working on building Uber’s chaos monkey (which was hard and took a while to build) and working with Netflix’s chaos monkey — it’s super nice to see Gremlin release this service so anyone can see the benefits of chaos engineering. I hope they add a “random chaos” feature to keep engineers on their feet. ;-)

    Hey folks, I work at Gremlin and we're super excited to announce this launch. Drop any questions, comments, or concerns, we're happy to help!

    Failure as a service doesn't make all that much sense considering that a many failure scenarios would make the target host inaccessible to Gremlin.

    How does Gremlin handle this?

    Is anyone aware of a chaos tool that isn't a SaaS (free or not) and doesn't require using Spinnaker like the current Netflix chaos tool does?

    So here is what I don't get about this stuff.

    What happens to the in-flight requests? Don't a few users run into random errors whenever a host is killed unexpectedly?

    You could have your loadbalancer retry everything that fails, but then wouldn't every single request in your app have to be idempotent?

    How do you prevent abuse of this tool?

    What infrastructure size does one need to have where this technique is beneficial? Genuinely curious where the threshold is.
