Michael Hausenblas, Red Hat developer advocate for OpenShift, still prefers the term Functions as a Service. In the push to expand the serverless capabilities of Kubernetes, Hausenblas, at KubCon in May, told us that one of the key desires for enterprises is to be able to host Amazon Lambda-like functionality internally as well as in public clouds. He expects as more users adopt serverless functions, that developers will increasingly become comfortable with function accessibility via APIs.

Hausenblas then detailed some of the changes this shift would bring to developers and their tools. "On the upside, I see a lot of positive developments so that it's pretty easy to actually write something. You can write it any language, as long as it's in Node.js. From a developer point of view, I don't think this is a big problem. It's more on the operational side. So if you actually think about who is going to be on call when you're operating that at scale , since you don't necessarily have any administrators around any more," said Hausenblas.
