Alternatives
A Rafay alternative with the full stack integrated
Rafay and FusioNative both help operators sell GPU cloud services. How they differ, where each fits, and what to ask in an evaluation.
Last updated · Fusionative
Short answer
FusioNative is a Rafay alternative for GPU cloud operators who want the cloud-operations layer and the infrastructure services beneath it in one product: tenancy, catalog, quotas and metering, plus KubeVirt VMs, Ceph storage, Cilium networking, model serving, security and observability, self-hosted or air-gapped.
Why teams look
Why teams look for a Rafay alternative
Integrated vs orchestration-first
Rafay orchestrates Kubernetes, VMs and Slurm on top of existing infrastructure and integrates with partners for storage and networking. Some operators prefer a suite that ships those layers too.
Control-plane location
Rafay offers SaaS and self-hosted controllers, including air-gapped installs. Operators choose based on where they want the control plane and who operates it.
Billing system of record
Rafay meters usage and exports chargeback data to the provider's billing system. Operators compare how each platform fits their own billing.
Checklist
What to look for in a replacement
- Tenancy model and isolation options for untrusted customers
- GPU sharing options and supported accelerators
- Metering units (GPU-hour, token) and the path into your billing system
- Which infrastructure layers are included vs integrated from partners
- Self-hosted and air-gapped operation, including licensing and upgrades
- Total cost at your node count, including support
Fit
Where FusioNative fits as a Rafay alternative
One suite from storage to catalog
Ceph, Cilium, KubeVirt, model serving, Shield security, observability and FinOps ship with the cloud layer.
Four platforms
AI Cloud, NEO Cloud, Sovereign AI Cloud and Air-Gapped AI Cloud from one product.
Self-hosted by design
The control plane runs on your estate, including offline.
When FusioNative is not the right choice
- You already standardized on separate storage and networking vendors and only want an orchestration layer above them.
- You prefer a vendor-hosted SaaS controller.
- You need specific integrations Rafay has certified, such as its NVIDIA AI Cloud-Ready validation.

FAQ
Frequently asked questions
Does Rafay support multi-tenancy and metering?
Yes. Rafay documents multi-tenancy, a self-service catalog, quotas, GPU sharing including MIG, token metering and chargeback export. The differences with FusioNative are in how much of the infrastructure stack is included and how it is deployed.
Can Rafay run air-gapped?
Yes. Rafay documents a self-hosted, air-gapped controller installation. FusioNative also supports fully air-gapped installs.
