I have come across a couple of posts with the title simplest serverless functions and my initial thoughts are …
- It is not that simple if you have to write up a config file to post a hello world function 🤦♂ !
- How easy is it to now extend this function to something more usable ?
So here we go again … this example is based on Apache OpenWhisk , an open source distributed serverless computing platform. However, a serverless system on your desktop/laptop is no different than spinning up a nodejs express app or a flask app. You are missing out on scale, performance and distributed nature of OpenWhisk. In order to make it even simpler, we will use IBM Cloud Functions, a managed version of Apache OpenWhisk.
In the next few posts, we will learn to extend this function to do something more usable. But wasn’t that easy !
See you next time ! In the meantime, read up on some serverless code patterns.
Max Katz, thanks for this post idea !

Nginx is a great piece of software that allows you to easily wrap your application inside a reverse-proxy, which can then handle server-related aspects, like SSL and caching, completely transparent to the application behind it.
