Author: Jase Batchelor

This section provides a comprehensive overview of the setup for core infrastructure and software used across projects. The primary objective is to create a standardized environment that can be easily replicated on virtual machines for demos. The setup is divided into three major themes: Systems, Software, and CI/CD GitOps. Systems The infrastructure is built using Radxa single board computers (SBC) and can be replicated virtually using Lima virtual machines for demonstrations.
