Backup Infrastructure: Some News from the Front!
Published on April 27, 2025 in Cloud
Following the launch of the new ScalarCloud production infrastructure, now distributed across 4 datacenters in Europe (and 2 in the United States), it is time for the backup infrastructure to evolve.
Objective: extend the security-through-distribution model already applied to production to the backup infrastructure.
In practical terms, instead of having one datacenter dedicated to backups and the others to production, we now have backup infrastructure distributed across 4 separate datacenters.
To ensure the lowest latency between each production site and its backup site, we conducted several rounds of measurements. The result:
– Gravelines will be backed up to Roubaix
– Roubaix will be backed up to Gravelines
– Limburg will be backed up to Strasbourg
– Strasbourg will be backed up to Limburg
Finally, SBG remains the standby site for production for now, while Limburg becomes the standby site for the backup infrastructure.
Hypervisor Update
Published on December 23, 2023 in Cloud
This is the final year-end update for all Proxmox VE hypervisors supporting the Public Cloud infrastructure of ScalarCloud.
Based on the tests we have conducted for more than a month, we will keep the Proxmox VE 7.4 branch on the Public Cloud production clusters for now.
We will schedule an update once all our tests are 100% conclusive. (In any event, the version has no client-side impact because this layer is not exposed.)
No service interruption is expected. The machines are live-migrated from node to node as the updates are carried out, then returned to their original location.
