Open-source Cozystack (CNCF project, created by Ænix) →Ænix Public Cloud, Private Cloud and AI Platform→Ænix builds, operates and migrates them.
Public cloud building is the engineering and go-to-market work of launching a customer-facing cloud product — VMs, Kubernetes, managed databases, object storage, and GPU — that external customers buy on a self-service, multi-tenant basis. It is for regional hosting providers, telecom operators, and specialty or sovereign cloud operators who want to move up-market without depending on a hyperscaler. Ænix builds these products on Cozystack, an open-source, Kubernetes-native platform (Apache 2.0) that runs VMs and containers on one Kubernetes API via KubeVirt, with Cilium eBPF networking, LINSTOR/DRBD storage, and Tenant-CRD multi-tenancy. Ænix delivers architecture, WHMCS billing integration, a self-service customer portal, and pricing and go-to-market design on top of the productized Ænix Public Cloud Platform.

Who it's forHosting providers, telecom operators, and regional / vertical / sovereign cloud operators — not hyperscalers
Core capabilityMulti-tenant architecture (Tenant CRD), self-service portal, service catalog (VMs, K8s, databases, S3, GPU), and WHMCS billing integration
Engagement timelineFree 30-minute discovery call and a 14- or 28-day readiness assessment. Provider scale: live in weeks once hardware is ready. Multi-region operator programmes: 3-6 month pilot, then 9-18 months.
Productized optionÆnix Public Cloud Platform — subscription from $1,250 per 10 nodes per month at provider scale; multi-region operator builds quoted per RFP
Hosting providers, telcos, and regional operators in 2026 face the question: how do we offer a credible cloud product to enterprise customers without becoming a hyperscaler? Demand for sovereign, regional, and specialty cloud is rising, but shipping one means solving multi-tenancy, billing, and self-service operations — not just standing up VMs.
Ænix builds customer-facing public cloud products on Cozystack — the open-source Kubernetes-native platform that powers Ænix Public Cloud Platform deployments at regional hosting providers and several other regional cloud launches.
Pairs with:Ænix Public Cloud Platform — WHMCS-integrated, productized installer, from $1,250 per 10 nodes per month for regional providers; the same platform at multi-region operator scale is a programme quoted per RFP.
Readiness assessment (14 or 28 days, fixed price) — architecture plus product and go-to-market emphasis
Build — at provider scale, live in weeks once the hardware is ready, with onboarding workflows and the first customer cohort following; for multi-region operator programmes, a 3-6 month pilot and then 9-18 months to full production
Phase 3 (optional) — managed-services arrangement during early customer ramp
Why Ænix
Cozystack-based deployments in production at multiple regional cloud operators
WHMCS production integration ready (two modes)
Multi-tenant operational expertise — production cloud is operationally different from internal IT
EU + Central Asia teams for regional alignment

"Running Nuvolos on sovereign bare metal meant we needed hyperscaler-grade multi-tenancy without the hyperscaler. Cozystack delivered exactly that — isolated tenants, shared GPUs, KubeVirt for legacy workloads — and it's why we can promise our customers infrastructure control, not just a workspace."
Alexandru PopescuCEO, Nuvolos
"Aenix has been a true partner in building Hikube, our Swiss sovereign cloud. Their technology is rock-solid, but what really sets them apart is how closely they listen and the quality of their support, always responsive, always invested in our success. As Hikube has grown, Aenix has grown with us. It's a partnership in the fullest sense."
Matthieu RobinCEO, Hidora & Hikube
"Cozystack has the energy of a young project and the strength of a mature platform — a rare and rather dangerous combination for the old guard. Ænix maintains it with the mindset of a hungry startup: they listen, move fast, and solve customer problems instead of sending them into a support maze."
Qasym MajenFounder, QOSI — Qazaq Open Source Initiative
"Cozystack is a powerful platform, but Ænix is what lets us squeeze every last bit of value out of it. Their team knows the product down to the source code, responds within minutes rather than days, and treats our roadmap as if it were their own. With Ænix behind us, we ship new managed services faster and sleep better — the platform just keeps running."
Evgeniy KozhukhovskiyCEO & Founder, Kubeone
"Working with Ænix feels less like buying support and more like gaining an engineering partner. They bring serious product and platform expertise to every conversation, flag risks before they become incidents, and help us turn Cozystack into real business results: shorter time-to-market, predictable operations, and infrastructure costs we can finally plan around."
SFSergey FedenyakCEO & Founder, GoHost.kz
"Cozystack helps us stay agile and spread opensource as far as we can reach."
Tamerlan AbuFounder, QOSI — Qazaq Open Source Initiative
Ænix created Cozystack, a CNCF project and CNCF Certified Kubernetes distribution, and maintains it with maintainers from other companies. Ænix sells three platforms built on it — Public Cloud, Private Cloud and AI — plus support and services.
Frequently asked questions
What does it take to launch a public cloud product on Cozystack?
A multi-tenant architecture using the Tenant CRD, a self-service customer portal, a service catalog (VMs, Kubernetes, managed databases, S3, GPU), billing integration via WHMCS, and go-to-market design covering pricing, onboarding, and SLAs. Ænix delivers this through a discovery call and a 14- or 28-day readiness assessment; at provider scale the platform is live in weeks once the hardware is ready, while multi-region operator programmes run a 3-6 month pilot and then 9-18 months to full production.
Who should build a customer-facing cloud product instead of reselling a hyperscaler?
Regional operators where local data sovereignty is a competitive advantage, hosting providers moving up-market from VPS or dedicated servers, telecom operators launching enterprise cloud, and industry-specific clouds (financial, government, AI). Hyperscalers are not the target audience.
How does billing work for a Cozystack-based cloud product?
Ænix provides a production-ready WHMCS integration supporting two modes — WHMCS as the customer-facing front, or Cozystack Dashboard as the front with WHMCS as the billing back-end — and can implement custom billing where needed. This lets operators meter and invoice multi-tenant consumption of VMs, Kubernetes, databases, storage, and GPU.
Is Cozystack open source and free of per-core licensing?
Yes. Cozystack is licensed under Apache 2.0 with no per-CPU or per-core licensing. It runs VMs and containers on a single Kubernetes API via KubeVirt, with Cilium eBPF networking and LINSTOR/DRBD storage. Ænix sells the Ænix Public Cloud Platform subscription and services on top.
What is the difference between this service and the Ænix Public Cloud Platform product?
The Public Cloud Platform is the productized foundation — multi-tenancy, the Cozystack Dashboard, the Ænix billing system and WHMCS integration, the installer — bought as a subscription from $1,250 per 10 nodes per month. The public cloud builder service is the engineering and go-to-market work around it: architecture for your estate, product-readiness, pricing and onboarding design. Multi-region operator builds are quoted per RFP.
How long until first customers are onboarded?
At provider scale, the platform is live in weeks once the hardware is ready, through the productized installer; pricing, onboarding workflows and the first customer cohort follow in parallel. Multi-region operator programmes run a 3-6 month pilot and then 9-18 months to full production. Both start with a free 30-minute discovery call and a 14- or 28-day readiness assessment. An optional managed-services phase can cover the early ramp.
