🔥Another CozySummit Virtual 2026 speaker worth your attention.
⚡𝐒𝐢𝐦𝐨𝐧 𝐊𝐨𝐮𝐝𝐢𝐣𝐬 — Founder and Engineer at ConfigButler — will present: “𝐖𝐡𝐚𝐭 𝐈𝐟 𝐄𝐯𝐞𝐫𝐲 𝐂𝐨𝐳𝐲𝐬𝐭𝐚𝐜𝐤 𝐂𝐡𝐚𝐧𝐠𝐞 𝐁𝐞𝐜𝐚𝐦𝐞 𝐚 𝐂𝐨𝐦𝐦𝐢𝐭?”
💪The idea: instead of Git driving the platform, the platform continuously writes its intent back to Git. Automatic. Silent. A durable, readable history of everything that happened — without changing how operators work.
Simon calls it Reverse GitOps. He’s building a real implementation at github.com/ConfigButler/gitops-reverser, and Cozystack’s platform-oriented Kubernetes API turns out to be a natural fit for the pattern.
If auditability and infrastructure history matter to your team — this talk is worth an hour of your time.

🔥Another CozySummit Virtual 2026 speaker worth your attention.
⚡Robert Galik — Senior Architect, founder of beby.cloud, and educator at Košická akadémia softvérového vývoja — will present: “Building a Sustainable Edge PaaS for Education: The BeBy.cloud Journey with Cozystack.”
💡The premise: students with no IT background, a low-energy edge cluster, and a full-stack Cozystack environment instead of a public cloud sandbox. No AWS bill. No abstraction layers hiding what’s actually happening. Just Kubernetes — the way it works in production at Deutsche Telekom, Siemens Healthineers, and AT&T.
Robert will show real stories of students going from zero to cloud-ready — and why a private edge cloud turns out to be a better learning environment than any managed service.
If you’re thinking about talent pipelines, cloud-native education, or what “pure Kubernetes” actually means as a foundation — this talk is for you.

Timur Tukaev, our COO, will be speaking at DevOpsDays Tashkent 2026 on May 15.
His talk: “How to Become a CNCF Project.”
It is not a theoretical overview. Cozystack was rejected the first time.
The application was weak, the story wasn’t clear, and the TOC wasn’t convinced. Two months later, our team spent a month studying successful applications, reading comments on failed ones and rewriting the narrative from the very begining.
The second application got Cozystack into CNCF Sandbox.
The talk covers what actually matters in a Sandbox application, how to talk to TAG and TOC, what signals show a project is ready and why joining a foundation like CNCF can be a growth strategy, not a bureaucratic detour.
May 15. Tashkent.

✨Another CozySummit Virtual 2026 speaker worth your attention.
Lu Servén Marín — SRE at AuthZed, maintainer of Thanos, Kilo, and various Prometheus community projects — will present: “Building a Multi-Cloud Service Mesh from the Ground Up with Kilo.”
The talk goes bottom-up: Kubernetes networking fundamentals, then what it actually takes to connect containers across nodes, geographic locations, and clusters using WireGuard and Kilo as the network fabric. From there, Lu builds a service mesh incrementally — static mesh first, then service discovery, then automated service mirroring.
No hand-waving. The talk also covers the challenges, limitations, and alternatives — which is usually the part that's most useful.

New Cozystack Highlights: Persistent Public IPs.
Today IP addresses in Kubernetes are ephemeral. You create a LoadBalancer service, you get an IP, you delete the service, the IP is gone. Recreate it and you get a different one. For anyone running real workloads on public IPs, that churn is a problem, and Cozystack users have been asking to fix it for a while.
The prototype shown at the last community meeting borrows the model everyone already knows from storage: just like a PersistentVolumeClaim binds to a PersistentVolume through a StorageClass, an IPAddressClaim binds to an IPAddress through an IPAddressClass.
What that unlocks:
— Reserve an IP before attaching it to anything, then bind it to a service via annotation
— Delete the service, the IP stays reserved and comes back to the same claim
— Move one reserved IP between services without losing it
— Contention policies: keep an IP alive after its claim is deleted, or release it back to the pool
— A reserved IP can't be stolen by another service
The design is deliberately platform-agnostic. The core controller handles the claim-to-address logic; a separate driver talks to the backend, MetalLB today, but the same pattern fits AWS Elastic IPs or anything else, much like a CSI driver for storage.
Still a prototype, but the direction is set: IP addresses become a first-class, reservable resource in Cozystack.

— Delete the service, the IP stays reserved and comes back to the same claim
— Move one reserved IP between services without losing it
— Contention policies: keep an IP alive after its claim is deleted, or release it back to the pool
— A reserved IP can't be stolen by another service
The design is deliberately platform-agnostic. The core controller handles the claim-to-address logic; a separate driver talks to the backend, MetalLB today, but the same pattern fits AWS Elastic IPs or anything else, much like a CSI driver for storage.
Still a prototype, but the direction is set: IP addresses become a first-class, reservable resource in Cozystack.

Persistent Public IPs in Cozystack: Reserve, Attach, Move
Timofei Larkin demonstrates a prototype API for managing public IP addresses as first-class Kubernetes resources.
Inspired by the PersistentVolume model, the design introduces IPAddressClaims, cluster-scoped IPAddress resources and IPAddressClasses. The…

VMware Exit Lab: European Workshop Tour has started today in Paris.
Over the next three weeks we’re running eight hands-on workshops across Europe.
They’re for teams that want to leave VMware without trading one lock-in for another.
In four hours you will:
1️⃣ build your own cloud on Cozystack, an open-source, Kubernetes-native platform (CNCF project)
2️⃣ migrate VM workloads off VMware
3️⃣ run managed databases, Kubernetes clusters and GPU workloads on the same platform
The format is hands-on, 10:00–14:00 local time. You can join 𝐢𝐧 𝐩𝐞𝐫𝐬𝐨𝐧 or 𝐨𝐧𝐥𝐢𝐧𝐞.
📍 Paris: 19 Oct
📍 Berlin: 23 Oct
📍 Warsaw: 26 Oct
📍 Copenhagen: 28 Oct
📍 Amsterdam: 30 Oct
📍 Milan: 2 Nov
📍 Madrid: 4 Nov
📍 London: 6 Nov
Seats per city are limited. Register here: https://u.to/eu-bIg
If your VMware renewal is coming up, spend four hours with us before you sign it.

Timur Tukaev @tym83 is at NVIDIA GTC Berlin this week, October 20–22.
Most of the conversations there are about models. We're interested in the layer underneath: how a bank, a telco or a hosting provider runs inference, fine-tuning and RAG on NVIDIA GPUs it owns — tenant isolation, per-team quotas, GPU usage that flows into the billing system they already run.
That's what we build at Ænix, on Cozystack: Apache 2.0, no per-GPU licensing.
If you're in Berlin and weighing hyperscaler AI APIs against your own GPU fleet, keeping AI inside a regulated perimeter, or selling GPU capacity as a provider — Timur is up for a coffee. Reach out to him directly.

Blockstor — a new storage control plane for Cozystack, written from scratch in Go.
LINSTOR-compatible: it keeps the LINSTOR CSI driver and Piraeus operator, and uses the Kubernetes API as the single communication plane between controllers and satellite nodes.
Andrei @kvaps walks through the migration tool, the blockstore CLI, synchronous DRBD replicas, RWX via NFS-Ganesha for AI workloads, and block-level live migration for VMs.
Plus the roadmap: BYOK encryption and a QEMU/QCOW2 backend.
Ends with Q&A: API server crashes, leader election, and running alongside LINSTOR.

Meet us at booth #305 — KubeCon + CloudNativeCon North America 2026
Ænix is bringing Cozystack: a CNCF Incubating project that turns bare metal into a private cloud — VMs, managed Kubernetes, databases and GPU under one API, on any Linux distro. Apache 2.0, no per-core fees, pricing that follows physical nodes.
Leaving VMware, retiring OpenStack, or building an AI platform on your own GPUs?
Timur @tym83 is on the floor — come talk it through.
Upstream components, no proprietary forks: if it runs on Cozystack, it runs anywhere.

Live VMware → Cozystack migration with Forklift, from our community meeting.
Andrei @kvaps shows the full path: connect a vSphere source, fetch the VM list, import — shutdown, disk snapshot, transfer, Cozystack entities created automatically. EFI and SATA bus translated on the way in.
Open source. The VMware exit, demonstrated, not promised.
