Virtuozzo Infrastructure
Turnkey OpenStack-based hyperconverged IaaS with tenant portal, metering and software-defined storage: a complete spec sheet, ranked last on our production experience.
Virtuozzo Infrastructure (renamed from Virtuozzo Hybrid Infrastructure in March 2026) packages KVM compute, software-defined block/S3/NFS storage and Kubernetes into a vendor-supported OpenStack distribution with an admin panel and a brandable tenant self-service portal. Virtuozzo bought OnApp in 2021 and the service-provider DNA shows: per-project metering (GPU-hour metering added in 7.3), S3 multi-tenancy, and off-the-shelf WHMCS/HostBill/CloudBlue billing integrations. Release 7.3 U1 (2026) introduced a built-in VMware migration tool with changed-block-tracking incremental sync. Because it exposes standard OpenStack APIs, the stock OpenStack Terraform provider and Ansible modules work unchanged.
The spec sheet reads well; the production experience is why it ranks last here. In our hands the platform felt unstable, and the company's acquisition trail (OnApp and Jelastic in 2021, among others) has, in our experience, left the acquired teams heavily restructured, in some cases with long-standing personnel appearing to be removed, and a product hierarchy and architecture that are confusing to navigate: it is not always clear which product, edition or console you are supposed to be using. Pricing is not public; there is no free tier.
Pros
- +Complete service-provider stack (tenancy, metering, billing hooks, S3) without assembling OpenStack yourself
- +Native CBT-based VMware migration (vSphere 6.x–8.x)
- +Standard OpenStack APIs mean existing tooling and skills transfer
Cons
- −In our experience: felt unstable in production
- −Serial acquisitions (OnApp, Jelastic, etc.) with the acquired teams heavily restructured and in some cases long-standing personnel appearing to be removed; confusing product hierarchy and architecture
- −No public pricing, no free tier, partner-only distribution
