I appreciate the explanation, but you misunderstand me. I get "serverless". I totally get lambda and some of the other open source clones of it. What i don't get about "Whisk" is if this is something that builds on top of existing serverless infrastructure that makes it better, or if it's it's own serverless infrastructure that you have to install on your own servers, or ... what. they're completely opaque about the actual server side infrastructure of this "serverless" platform.
