Your Own Little HA Cloud at the Edge (or at Home)
summary
Builds a small HA cloud that runs containers and VMs across mixed hardware from Raspberry Pi to dual Xeon boxes, using LXD for instances, Ceph for distributed storage and OVN for networking, with control planes sized at three nodes minimum. Demonstrates bootstrapping a three-node LXD cluster, evacuate/restore workflows, live VM migration, and Juju bundles that deploy Ceph/OVN/LXD and wire them together. Production rack example: three dual‑Xeon servers, ~48 TB storage, 10 Gb networking, ~250 USD/month bandwidth; the setup boots, survives node loss and is recoverable.
