Bare metal AI platform layer

The tenant platform on top of your bare metal stack

GPU cloud operators have a bare metal stack: an inventory of BMC-managed servers, a provisioning system, a cluster manager, and a fleet tool. Saturn Cloud sits above all of that and gives tenants a self-service AI platform. We work with Mirantis k0rdent, SUSE Rancher with OpenNebula, and Spectro Cloud Palette. The stack underneath is your call.

Where Saturn Cloud sits

Above the bare metal stack, not inside it

Saturn Cloud is not a bare metal provisioner. We do not drive BMCs, image disks, or run Ironic. The companies and projects in the row below us do that well, and we partner with them. Saturn Cloud is the tenant-facing platform on top: the portal customers log into, the workspaces they run, the jobs they schedule, and the invoices they receive.

Tenant portal, self-service workspaces

Customers sign up, request resources, launch JupyterLab or VS Code on H100s and H200s, and run distributed training. None of that depends on which bare metal stack is underneath.

Allocation-based billing

Tenants are invoiced for the hardware they hold over time, not the workloads they run. Saturn Cloud snapshots the allocation ledger from whichever BMaaS stack you operate. See GPU chargeback and metering.

Stack-agnostic by design

The same Saturn Cloud product runs on Mirantis k0rdent, on SUSE Rancher with OpenNebula, and on Spectro Cloud Palette. Operators pick the stack that fits their hardware and team, and we plug into it.

One operator console across the fleet

Per-tenant usage, idle workloads, and quota in one admin view. The same fleet console regardless of which projects manage the layers underneath.

Reference stacks

Three bare metal stacks Saturn Cloud runs on

Each stack is built around a vendor or project that owns the lifecycle of physical machines. Saturn Cloud sits above all three the same way and bills against whichever allocation ledger the stack exposes.

Mirantis k0rdent

Saturn Cloud Tenant portal, workspaces, jobs, billing

▲

k0rdent Fleet manager (Mirantis)

▲

Cluster API + Metal3 K8s cluster lifecycle on bare metal

▲

Ironic Drives the BMC, images the box

▲

GPU hardware BMC, NICs, storage

Kubernetes-native end to end. Allocation ledger is the Metal3 BareMetalHost CRD. The right pick for operators who want everything to look like Kubernetes objects.

What changes when you add Saturn Cloud

What the bare metal stack gives you, and what's still missing

Capability	Bare metal stack alone	With Saturn Cloud on top
Provisioning bare metal nodes	Yes (this is its job)	Saturn Cloud delegates this to the stack
Managing Kubernetes clusters	Yes	Saturn Cloud delegates this to the stack
Tenant signup and self-service portal	No	Yes
AI workspaces (JupyterLab, VS Code, jobs)	No	Yes
Per-tenant allocation billing and invoices	No (data is there, but not the billing layer)	Yes
Tenant-internal showback for their own teams	No	Yes
Cross-fleet operator console	Partial (cluster-level, not tenant-level)	Yes, tenant-level
