I checked the nuvolaris.io website. It looks like a distro to run FaaS on any Kubernetes infrastructure, including bare-metal (that would save a lot of money). The fact that it has a whole architecture in a box with simple commands could make it worth it a try. I installed on my Mac and it worked at first try with all data backends, Kafka queues, S3-compatible storage... Need a weekend to try it.
To spare people, this is code from Nuvolaris which is a distribution of Apache openwhisk
