Do you want to use a FaaS or just toy with making your own? If you just want to use something check out OpenFaaS, it's very easy to get started and is well documented: https://www.openfaas.com/ https://www.openfaas.com/ If you want to build your own FaaS, I'd still explore OpenFaaS as its creator has documented a lot of its creation and you will soon discover the critical things you'll need to figure out for building your own similar service (i.e. stuff like sandboxed execution environment, API gateway, scaling up and down functions, etc.).
