Building a Sustainable Edge PaaS for Education: The BeBy.cloud Journey with Cozystack
summary
Ultra‑low‑power education PaaS built on CM4/CM5 nodes runs a Talos + KubeStellar stack with Longhorn/CEPH, Cilium, FluxCD and a WASM operator; a desk‑mounted nine‑node cluster consumes ~40 W and survives node failures while serving student projects. Students move from zero experience to Docker, CI/CD and “pure Kubernetes” deployments, and ARM porting plus NVMe boot and optional AI accelerators prove the edge platform is functional and reproducible.
