Заменили ноду в кластере RabbitMQ — и через месяц потеряли регион OpenStack

Короткая история про то, как штатная замена ноды оставила quorum-очереди с двумя членами вместо трёх, и почему cluster_status этого не показывает. Стенд: OpenStack Caracal (2024.1), развёрнут kolla-ansible. RabbitMQ — кластер из трёх нод, quorum-очереди.

On Superuser, Mayflower explains how they built a hybrid private cloud as an AI factory, using open infrastructure to support one of the world's largest interactive platforms.

Their architecture unifies virtual machines, bare metal, GPUs, and Kubernetes under a single @OpenStack based platform.

The greatest trick the hyperscalers ever pulled was to convince you you needed their 200 services.

Great post by Bernd Erk from Netways on the illusion that you can't leave hyperscalers in favor of more local and sovereign clouds.

Die 300.000 CPU-Kerne der T-Mobile-VMs rufen nach Proxmox oder Openstack.

Aber man kann natürlich versuchen mit Greedcom zu verhandeln.

" #OpenStack 's presence continued in the TOP500 list of the world's most powerful supercomputers, including StackHPC clients:

#67: Sunrise at the UK Atomic Energy Agency and Cambridge University.
#68: Zenith at Cambridge University.
#75: MUSICA at Austrian Scientific Computing.
#111: Dawn at Cambridge University AI Research Resource.
#409: Toubkal at the Mohammed VI Polytechnic University in Morocco."

The most common question at our OpenStack + StarlingX booth at KubeCon + CloudNativeCon India wasn't "how do I deploy it?" It was "how do I contribute?"

Jimmy McArthur, Director of Business Development at the OpenInfra Foundation, shares his takeaways:

"I have never seen open source more relevant, or more necessary, than it is right now."

OpenInfra Foundation board member Johan Christenson has spent two decades building European cloud infrastructure. In this piece for Enterprise Times, he makes the case for why open source projects like OpenStack and Kubernetes are the neutral, collaborative foundation Europe needs to reclaim its digital future.

OpenStack Ironic has patched CVE-2026-43003, a command injection where a malicious partition image could execute crafted binaries within a chroot during bootloader installation on BIOS-booted nodes. Because Ironic provisions physical hardware, a compromised image is a foothold on real machines, not just a VM. Where does image validation sit in your bare-metal pipeline?

Unser Vortrag vom SCS Summit ist online: „OpenStack to OpenStack - Moving to a new home“

Michel Raabe und Daniel Pfanz von Körber Pharma zeigen anhand eines Praxisbeispiels die Migration von Red Hat OpenStack zu einer neuen OpenStack-Umgebung auf Basis von OSISM inkl. der Herausforderungen, die bei einem solchen Wechsel auftreten können.
