Cloud computing is growing, and with it a whole bunch of new frameworks and terms, such as “serverless” and “Function as a Service.” While a lot of these frameworks are supplied by big companies like Amazon and Google, there are projects such as OpenFaaS which allow you to run a Function as a Service platform on your own machine(s). What’s more, OpenFaaS also allows for easily extending the platform to support other languages. Because OpenFaaS revolves around functions, it made perfect sense to add support for the first functional programming language, Lisp, by using the wonderful Racket environment. And now you too can make your own serverless Racket function! Let’s try it out.
