Thanks to everyone who came out to my talk at Clojure PDX last night. Code for the demo project is on Github and the slides are available here.

In part one and part two of this series, we looked at how to build a ClojureScript environment that we can deploy to AWS Lambda and the API Gateway that will respond to the outside world as a web service. With that done, today we’ll see how to go about deploying it.

One of the common synonyms for “serverless” is “Function as a Service”: there is a place in the cloud that we upload a function to, and it runs when some event is triggered. Web services are easily modeled as functions in Clojure/Script, so that’s how we’re going to set ours up.

Maybe you’ve heard all the hype about serverless computing. Maybe you’ve heard disturbing rumors that serverless apps do in fact run, somewhere, somehow, on servers. Maybe you were ok with all that, but not with writing AWS Lambda functions in Java or JavaScript. Me too. Let’s do it in Clojure.
