One hour with Andrei Kvapil, the creator of Cozystack: how a working provider widens the catalog on the racks it already owns — beside the platform it already runs, keeping its own billing and its own panel.
You own the racks, you run the platform, and you have the customer relationships. What customers ask for keeps widening — managed Kubernetes, managed databases, object storage, GPU, self-service, predictable billing — and every service you cannot offer is a conversation that ends somewhere else. This session is about closing that gap without rebuilding the business underneath it.
A customer asks whether you do managed Postgres, and the answer is no. A renewal quote arrives with a number on it that changes the maths on your VM margin. The platform works, but keeping it working is somebody's entire job. Or the panel your team wrote years ago still runs provisioning, and every new service turns into another month of glue code.
None of these calls for a rebuild. They call for one more platform beside what you run, and a way to sell what it can do.
Cozystack is an open-source cloud platform and CNCF Sandbox project that turns your hardware into a catalog: virtual machines, managed Kubernetes, managed databases, S3-compatible object storage and GPU — each one ordered from a self-service panel, provisioned automatically, backed up and monitored. You set the price.
On top of it, Ænix modules turn the platform into a business: billing and usage metering, a hosting panel, WHMCS and custom integrations, and a migration plan that moves customers one at a time.
Not pilots. Production platforms selling to real customers, built on the same foundation the session walks through.
A Swiss cloud provider moved off a hypervisor stack and a Jelastic/Virtuozzo legacy onto a full commercial public cloud — virtual machines, managed Kubernetes, databases and GPU, sold under its own brand. Its own engineers became Cozystack maintainers.
A European academic-computing platform moved off a public hyperscaler onto owned bare metal and kept a single Cluster API spanning bare metal, a hyperscaler and a sovereign Swiss cloud — with fractional GPU sharing across jobs.
Both are anonymised at the customer's request. Andrei walks through what each of them actually did — and what he would do differently on your stack.
Forty-five minutes of practice, then your questions.
The catalog, and what it earns. Managed Kubernetes, databases, object storage and GPU as sellable SKUs: what each takes to turn on, what to price it against, and which ones sell first.
A second platform beside your current one. How Cozystack sits next to VMware, OpenStack, Proxmox or Virtuozzo without a cutover: where the two stacks touch on the network, on storage and at the load balancer.
Moving customers across, one at a time. Migration in practice — what moves cleanly, how long a per-customer move takes, and the workloads Andrei would leave exactly where they are.
Billing, metering and your panel. Usage metering out of the platform and into your invoicing. WHMCS as a worked example, custom panels over the API, and tenant lifecycle tied to payment status.
GPU as a product. Renting a whole card or a share of one: passthrough, vGPU and fractional sharing (HAMi), what each isolates, and what you can put in a customer contract.
The pilot, and the first ninety days. One node, roughly two weeks to a working environment, and the pilot becomes your production — no reinstall, acceptance criteria agreed by both sides.
The session ended with a live Q&A with the speaker.
A realistic next catalog — the services worth adding first, and what each one is worth to you.
A clear-eyed view of billing, usage metering and panel integration — how they work in practice.
A migration path that keeps your customers online and your calendar your own.
A pilot you can actually start — one node, two weeks, and it becomes your production.
Providers that already sell infrastructure and are deciding what to sell next. If your platform today is VMware, OpenStack, Proxmox, Virtuozzo, CloudStack, OpenNebula or something you wrote yourself, the session was built around your situation.
Especially the people who own the service catalog and the number under it:
Andrei created Cozystack, the open-source cloud platform and CNCF Sandbox project, after more than fifteen years of building clouds and high-load infrastructure. He contributes to Kubernetes, KubeVirt, Cilium and LINSTOR, and speaks at KubeCon and other industry events. At Ænix, he helps providers across Europe turn their infrastructure into commercial cloud services.
