Ask HN: FaaS (Function as a service) for Ruby? (2017)

Hi Folks, It has been a year since I last asked this question, so I thought I'd put it out there again! Do you use / know of any services like AWS Lambda that supports Ruby out of the box? I've been playing with AWS Lambda using travelling Ruby and Mruby, but have hit issues ( I need to be able to use native gems). Whilst it is possible to use native gems w/ travelling ruby the setup is fragile. Thanks in advance for your input!
