What looks particularly funny that it's OpenFaaS examples, such as in this post: figlet service. Several years ago it was simple binary, which you could invoke in console to produce fancy-stylized string. Now, same functionality require running figlet function-as-a-service inside Docker container inside Kubernetes cluster. I understand, that's merely an example, but nevertheless.

Kubernetes is optional - Docker Swarm (which some people prefer for its simplicity is also available) - basically yes binaries get wrapped in containers now for build/ship/run.

You're right though it is just an example - one of many in the function store. OpenFaaS can run any binary as a function - that means that we can strip back all the complexity needed to utilise ImageMagick for instance as a function by making it a function that works over stdin/stdout. Normally that would have involved a Node.js runtime and native compilation packages.

Here's the example: https://blog.alexellis.io/serverless-imagemagick/
