Building the European Weather Cloud with Open source software : An end to end journey.
summary
European Weather Cloud runs two on‑site OpenStack clusters (initially Rocky then upgraded towards Ussuri), fronted by Ceph Nautilus storage and a federation target of ~34 member states. Current footprint is ~3,000 vCPUs, ~1 PB Ceph, dozens of OSDs and Nvidia Tesla V100 GPUs; a 25‑node Ussuri test deployment and live migration of a Rocky cluster complete with zero‑downtime reconfiguration. Deploy uses TripleO, moves from Docker to Podman, and resolves OVN/Octavia floating‑IP, LACP and CentOS 7→8 integration issues.
