ArtCloud engineers certified in Cozystack: private clouds at corporate grade

ArtCloud engineers have passed the AENIX Certification for Cozystack — Fundamentals (CCF) exam: Evgeny Bratkovsky, Aleksandr Zubik, Daniil Zhytnitski and Siarhei Kisialeu confirmed their expertise in Cozystack — an open cloud platform built on Kubernetes, developed under the umbrella of the CNCF (Cloud Native Computing Foundation).

What Cozystack is

Cozystack is a free open source cloud platform that turns a set of your own servers into a full-fledged private cloud. The project is part of the CNCF ecosystem and is positioned as a "self-hosted alternative to AWS" and an open replacement for VMware.

On the customer's hardware the platform provides, through a simple API:

- Kubernetes clusters — managed, isolated per tenant, deployed in minutes;
- databases as a service — PostgreSQL and other DBMS with replication, backups and monitoring out of the box;
- virtual machines and containers on one platform — with live migration and replicated storage;
- S3-compatible object storage, load balancers, HTTP caching and other services.

The platform is assembled from proven open source components (Talos Linux, Ceph, KubeVirt and others), requires no external SaaS in the management contour, and runs entirely on the customer's hardware. Cozystack holds Kubernetes Conformance and CIS Benchmark certifications and undergoes PCI DSS, GDPR and DORA compliance reviews.

Why it matters for business

A private cloud on Cozystack answers the questions every growing company eventually faces:

Your data stays with you. The management contour does not depend on external clouds — the infrastructure lives entirely on your servers, in your jurisdiction. This is critical for banks, healthcare, the public sector and everyone working with personal data.

Predictable economics. Instead of growing cloud bills — your own hardware, with the platform squeezing the maximum out of it. A typical scenario is migration from VMware after the licensing change: virtual machines move with a migration tool rather than being rewritten.

Speed for development teams. A test contour, a Kubernetes cluster or a database is provisioned on request in minutes — within your quotas and without tickets to someone else's support. No more "the environment will be ready in two weeks".

AI-ready. The platform is designed for AI infrastructure: GPU resources are distributed across teams and projects, and combined with ArtCloud products (ZuBrIQ, AI agents) the company gets a closed contour of "infrastructure + data + AI".

Expertise, confirmed by certificates

The CCF certification covers platform architecture, cluster deployment, tenants, storage and networking, troubleshooting and operations. For clients this means that private cloud design and maintenance at ArtCloud is done by engineers whose knowledge has been verified by the platform vendor.

ArtCloud has previously used the Kubernetes and Talos combination in production projects; the certification formalizes this experience. The company's cloud practice includes design, implementation and 24/7 infrastructure operations with observability and capacity headroom.
