A cloud platform for hosting providers lets a traditional shared, VPS, or dedicated-server business launch hyperscaler-class cloud products while keeping its direct customer relationships, pricing flexibility, and margin. Aenix delivers this with Cozystack, an open-source Kubernetes-native platform that runs VMs (via KubeVirt) and containers on one API, with Cilium eBPF networking, LINSTOR/DRBD storage, and Tenant-CRD multi-tenant isolation. It is productized as the Ænix Public Cloud Platform, with WHMCS-integrated billing, tenant lock and suspension, a service catalog beyond VMs (managed databases, S3, GPU), and migration tooling from VMware, OpenStack, and Virtuozzo. Apache 2.0 licensing means no per-CPU fees, so hosting margin is preserved.
Hosting providers in 2026 face customer demand for cloud capabilities competitive with hyperscalers but with the customer-relationship advantages and pricing flexibility that hosting providers already have. The architectural answer is a Kubernetes-native platform with multi-tenant customer isolation, billing integration, and a service catalog beyond VMs — Cozystack’s design center.
Pairs with: Ænix Public Cloud Platform — modern alternative to OpenStack for hosting providers. WHMCS-integrated billing, tenant lock/suspension, fast feature delivery, productized installer, migration tooling from VMware/OpenStack/Virtuozzo. Entry from $1,250/month support tier. Public production customers: GoHost.kz, HDReady, Beby Cloud, HiKube, UseTech, Cloupard, Cloudsy. See Partner Program for up to 40% margin on resold engagements.
See the customer portal for yourself. The Cozystack Dashboard console is the actual Ænix Platform customer frontend, running entirely in your browser with demo data — no signup, no cluster, no setup.

Frequently asked questions
Why would a hosting provider move from VPS to a Kubernetes-native cloud platform?
Customers increasingly expect cloud capabilities competitive with hyperscalers — managed databases, object storage, GPU, and self-service. A Kubernetes-native platform adds these as a single service catalog while the provider keeps its direct customer relationship and pricing flexibility.
Does Cozystack support both virtual machines and containers?
Yes. Cozystack uses KubeVirt to run VMs and containers on one Kubernetes API, so a provider can serve traditional VM customers and modern container workloads from the same platform and operations team.
How does billing integration work for hosting providers?
The Ænix Public Cloud Platform includes WHMCS integration in two modes: the native Cozystack UI and a Cozystack Dashboard customer-facing frontend. It also supports tenant lock and suspension tied to billing status.
Is there per-CPU or per-core licensing?
No. Cozystack is Apache 2.0 licensed, so there is no per-CPU or per-core fee. This preserves hosting margin compared with proprietary virtualization platforms that license by socket or core.
Can a provider migrate existing workloads from VMware, OpenStack, or Virtuozzo?
Yes. The Ænix Public Cloud Platform ships with migration tooling from VMware, OpenStack, and Virtuozzo, allowing providers to move existing customer workloads onto the new platform.
How is multi-tenant customer isolation handled?
Cozystack provides production-grade isolation through a Tenant CRD, giving each customer a bounded, isolated environment on shared infrastructure — the foundation for selling cloud products to many customers safely.
