Datacenter in a Suitcase - a real small edge case - Mario Fahlandt
summary
A portable datacenter fits into a suitcase by stacking ARM compute modules on a MiniITX Clusterboard, running a lightweight Kubernetes control plane from Kubermatic installed with KubeOne, and using KubeVirt to host VMs for non-container workloads. Demonstrated limits include four-module CPU counts, VM and controller overhead, eMMC vs NVMe storage gaps on Raspberry CM4, USB3/USB2 cable pitfalls, missing Ubuntu ARM packages, and a €220 per-module future 8-core/32 GB option; use cases: field research, retail edge, emergency sites.
