We recently witnessed an AWS outage. I then saw an article that called for European digital sovereignty in the context of the outage, but those are two different concepts.
To be safe from an outage in a single zone of a cloud provider, treat it as a failure domain. You protect yourself with data replication to another zone (ideally at a different cloud provider) and an HA mechanism between the two. That is ‘availability’. ‘Digital sovereignty’, on the other hand, is about having control over your data’s fate, in a legal and physical sense, including knowing that no one else can silently access it.
Over to LINBIT, the big exciting news this last week is that the team has finished the ReadWriteMany (RWX) support for persistent volumes in Kubernetes. As I am writing this text, it is available with the 2.10.0-rc.4 release of the linstor-operator. I expect the final release any day now. It allows one to attach a (file access) persistent volume to multiple containers concurrently in a Kubernetes cluster. You should only enable it if your workload needs it, since it adds an NFS layer to the I/O stack, which affects access performance. When needed, however, this considerably eases the deployment of such RWX volumes.
I can share some news regarding upcoming events, one in Italy and another online. LINBIT Developer Rene Peinthor and I will present in Milan at the CloudStack Collaboration Conference next month, which is an event we’re also sponsoring. Following the CCC, Moritz will speak at CozySummit Virtual 2025 on the 3rd of December, which is a virtual event. We have published more information about both events on our blog for those who want to learn more.
Regarding software updates, we recently released drbd-reactor v1.10.0.
