DESCRIPTION:The EU Cloud Sovereignty Framework breaks digital sovereignty 
 into eight objectives and rates each on the SEAL scale. Your weakest objec
 tive decides your grade\, not your average. So a single closed component c
 an cap the score of everything built on top of it.\n\nThis talk takes one 
 unglamorous layer and runs it through that test: highly available block st
 orage.\n\nThe technical picture first. DRBD replicates block devices synch
 ronously across nodes inside the Linux kernel\, so a virtual machine or a 
 container mounts what looks like a local disk while every write is committ
 ed on more than one node. LINSTOR orchestrates LVM\, ZFS\, and DRBD across
  a cluster and decides where replicas live. No proprietary appliance sits 
 in that path\; the replication runs on the same commodity servers as the w
 orkloads. The stack ships as LINBIT SDS with drivers for Apache CloudStack
 \, OpenStack\, Kubernetes\, OpenNebula\, Proxmox VE\, and XCP-ng\, which m
 atters for the framework's lock-in objective: the storage layer does not d
 ecide which virtualization platform you can run.\n\nThen the audit. Using 
 DRBD and LINSTOR as a worked example\, open source and developed mainly in
  Austria\, I go through the objectives one by one: which ones an open sour
 ce component satisfies by construction\, which ones it merely enables whil
 e the operator still has to do the work\, and which ones it cannot help wi
 th at all.\n\nThe framing is European\, but the questions are not. An oper
 ator in Asia or the Americas asks the same things in different vocabulary:
  Economic security\, supply chain resilience\, technological leadership. A
 ttendees leave with a way to audit their own infrastructure component by c
 omponent\, rather than trusting a label.
