The idea is inspired by the following blog post (https://blog.alexellis.io/your-serverless-raspberry-pi-cluster/) where the OpenFaaS framework is deployed on a set of Raspberry Pi boards configured in a cluster.
The main concept is the same, but instead of using physical boards, we'll have a set of VM nodes. The goal is to have OpenFaaS running in a virtual cluster with QEMU as a hypervisor.
- No additional costs for hardware (Raspberry Pi boards, Ethernet dongles, SD cards, cables, etc)
