7 Best Bare Metal GPU Provisioning Platforms for AI Clouds

Summary

  • The software tooling for provisioning and orchestration, not the hardware, is the critical factor that determines how quickly you can launch a profitable AI cloud.
  • Evaluate bare metal platforms on five key production metrics: provisioning speed, lifecycle management, Kubernetes integration, network automation, and tenant isolation.
  • With average enterprise GPU utilization sitting between 5-37%, the biggest opportunity for ROI is in efficient orchestration and secure tenant isolation to maximize hardware usage.
  • Full-stack platforms like vMetal are designed to close the "Metal-to-Model" gap, unifying the entire stack to turn racked servers into revenue-generating tenant clusters.

You've racked the servers. The GPUs are seated, the cables are run, and the power is on. And then the real work begins.

"Setting up a Kubernetes cluster on bare-metal with GPU workloads can be a challenging task" — that's the blunt verdict from engineers who've done it. And they're right. The hardware is just the entry ticket. What determines whether you ship a profitable AI cloud in 90 days or 18 months is the tooling layer: the software that automates bare metal GPU provisioning, orchestrates Kubernetes at scale, isolates tenants securely, and keeps the whole fleet healthy without a team of SREs babysitting every node.

The gap between "servers in a rack" and "revenue-generating AI cloud" is what we call the Metal-to-Model gap. Every platform on this list exists to help you close it — but they do it in very different ways, at very different layers of the stack.

To cut through the noise, we evaluated each platform against five criteria that actually matter in production:

  • Provisioning Speed — How fast does a racked server become a usable GPU node?
  • Lifecycle Management — How much of discovery, OS install, upgrades, and decommission is automated?
  • Kubernetes Integration — Native K8s experience, or a bolted-on afterthought?
  • Network Automation — Does it handle VLANs, VXLANs, and tenant network isolation, or do you wire it yourself?
  • Tenant Isolation — Can you serve multiple customers or teams on shared hardware securely, without performance degradation?

Let's get into it.

1. vMetal by vCluster Labs — The Full-Stack Orchestration Layer

Best for: AI cloud providers, neoclouds, and enterprises building internal AI factories who want the shortest path from GPU rack to billable tenant cluster.

vMetal is not a hardware provider. It's the software layer that makes any bare metal GPU fleet behave like a hyperscaler cloud. Built by vCluster Labs — the team behind 30.1k GitHub stars, 100K+ GPU nodes in production, and a spot in the NVIDIA DGX SuperPOD reference architecture — vMetal is purpose-built to close the Metal-to-Model gap.

Provisioning Speed: Zero-touch. A server arrives in the rack, and automated PXE boot, OS installation, and machine registration handle the rest. No manual SSH, no hand-crafted Ansible playbooks, no ticket queue.

Lifecycle Management: Centralized control over the complete GPU server lifecycle — from initial discovery through provisioning, health monitoring, OS upgrades, node repurposing, and eventual decommission. The vMetal blog post captures what this means in practice: a single platform for every operational event that touches your physical fleet.

Kubernetes Integration: This is where vMetal separates from every other bare metal provisioning tool. It ships vCluster Standalone — a certified Kubernetes distribution that runs as a single binary directly on Linux, with no dependency on k3s, kubeadm, or k0s underneath. You get a production-grade K8s cluster on bare metal without an intermediate orchestration layer adding complexity and failure modes. On top of that, the vCluster Platform creates fully isolated, CNCF-certified tenant clusters as lightweight processes — each with its own API server, etcd, RBAC, and CRDs — spinning up in seconds, not hours.

Network Automation: Native integration with Netris for automated VLAN, VXLAN, VRF, and ACL configuration. Tenant network isolation is programmatic, not a manual firewall rule exercise.

Tenant Isolation: The full isolation spectrum is covered: shared nodes → private nodes → dedicated nodes → vNode (currently in private beta) kernel-native workload isolation. vNode adds seccomp, cgroups, namespaces, and AppArmor per workload without a hypervisor penalty, meaning you get container breakout protection at bare metal GPU performance.

Proof points: Lintasarta launched Indonesia's leading GPU cloud with 170+ tenant clusters in 90 days. Boost Run stood up their AI cloud in under 45 days with zero new platform engineering hires. CoreWeave — one of the world's leading GPU clouds — is a vCluster Labs customer.

Auto Nodes (Bare Metal Karpenter) rounds out the picture: GPU nodes are automatically provisioned via Terraform when tenants schedule workloads, and deprovisioned when they don't. You only pay for hardware that's earning.

2. CoreWeave — Specialized High-Performance GPU Cloud

Best for: Large-scale LLM training and inference workloads requiring massive, tightly coupled GPU clusters with HPC-grade interconnects.

CoreWeave is the benchmark GPU cloud for serious AI workloads. Their infrastructure is built around NVIDIA H100s and A100s on HPC-optimized hardware with high-speed InfiniBand interconnects, and they offer a managed Kubernetes experience on top of bare metal — making them one of the few providers that clears the bar on all five evaluation criteria as an integrated cloud.

Provisioning is instant for end users (it's fully managed), Kubernetes integration is first-class, and the hardware density is purpose-built for the largest training runs in the market. Notably, CoreWeave itself is a vCluster Labs customer, using the technology for tenant cluster orchestration — a meaningful signal about what production-grade bare metal GPU provisioning looks like at scale.

The tradeoff: CoreWeave is a destination, not a tooling layer. You're deploying on their infrastructure, not your own. If you're building your own GPU cloud, you'll need a provisioning platform like vMetal on top of your hardware.

3. DigitalOcean — Developer-Friendly Bare Metal GPUs

Best for: Teams that want raw hardware access from a trusted cloud brand and are ready to build their own orchestration layer on top.

DigitalOcean's Bare Metal GPU offering provides single-tenant, dedicated access to serious hardware: NVIDIA HGX H100, HGX H200, and AMD MI300X configurations, each with 8 GPUs, 2,048 GiB of system RAM, and 61+ TiB of NVMe storage. You get full root-level control to install whatever software stack you need.

The catch is in what's not included. Provisioning is handled via contract and the sales team — there's no self-service API for zero-touch automation. Security defaults are minimal (no default firewall). And lifecycle management is your problem to solve. DigitalOcean gives you the powerful raw hardware; the orchestration, tenant isolation, and Kubernetes layer are yours to build.

That's not a knock — it's a positioning statement. For teams that know exactly what they're deploying and have the engineering capacity to manage the software stack, DigitalOcean's bare metal GPUs are a compelling foundation.

4. Equinix Metal — Foundational Global Bare Metal

Best for: Enterprises needing a globally distributed bare metal footprint as the foundation for a private or hybrid AI cloud.

Equinix Metal combines dedicated hardware with cloud-like deployment speed across a global network of data centers. Their strength is breadth: a wide range of customizable hardware configurations, deep integration with major network and cloud providers, and a footprint that lets you put GPU compute close to your users.

It's worth noting the market context here. A wave of customers migrated away when Equinix made changes to their bare metal offering, which highlights a critical principle for AI cloud builders: your provisioning layer should be hardware-agnostic. A platform like vMetal that sits above the physical infrastructure means you're never locked into a single bare metal provider — you can migrate fleets, add new regions, or swap hardware vendors without rebuilding your automation from scratch.

Equinix Metal excels as the physical layer. The orchestration, Kubernetes, and tenant management layers still need to be handled separately.

5. Lambda Labs — GPU Cloud for AI Researchers

Best for: Individual researchers, academics, and small teams who need quick access to powerful GPUs with minimal infrastructure overhead.

Lambda Labs carved out a strong niche by focusing relentlessly on the AI researcher experience. Pre-configured environments with popular ML frameworks mean you're running training jobs, not configuring CUDA drivers. Pricing is transparent and straightforward, without the hidden fees that plague larger cloud providers.

Lambda offers both dedicated GPUs in bare-metal and virtualized configurations, though the bare metal GPU provisioning layer is fully managed — you interact with the environment, not the infrastructure. That's the right tradeoff for a solo researcher. It's not the right architecture for an AI cloud provider trying to build and monetize GPU infrastructure with secure tenant isolation.

6. Mirantis k0rdent AI — Enterprise-Grade AI Platform Software

Best for: Enterprises evaluating full-stack software platforms for building managed AI infrastructure on bare metal.

Mirantis k0rdent AI is the most direct software-layer competitor to vMetal in this list. Its goal is similar in scope: automate bare metal GPU provisioning, deliver tenant isolation and network isolation, and provide a self-service developer experience without hyperscaler-level investment.

The platform partners with Saturn Cloud for an AI application layer on top, targeting enterprises that want a one-vendor answer to the Metal-to-Model gap. For teams evaluating this category, k0rdent AI represents the "enterprise managed solution" end of the spectrum — useful to benchmark against when deciding whether to build on an open, composable stack like vMetal or a more vertically integrated offering.

7. OVHcloud — Cost-Effective Bare Metal at Scale

Best for: Budget-conscious organizations that need raw bare metal servers at scale and are prepared to manage the software and orchestration layers independently.

OVHcloud is one of the most price-competitive options for bare metal server procurement globally. Their catalog spans a wide range of hardware configurations, with a strong presence in Europe and North America. If your primary constraint is cost-per-GPU-hour on the hardware side, OVHcloud warrants serious consideration.

The tradeoff is identical to DigitalOcean: you get the hardware, and the rest is yours to build. There's no zero-touch provisioning, no native Kubernetes integration, no tenant isolation framework included. OVHcloud is a foundation layer, not a full-stack solution — which means it pairs well with a provisioning platform that fills those gaps.

Decision Matrix: Matching AI Workloads to Provisioning Architecture

Not every workload has the same infrastructure requirements. Here's how to map your use case to the right architecture:

Workload Key Needs Recommended Hardware Layer Recommended Provisioning Layer
LLM Training Massive parallelism, InfiniBand, stable long-running clusters CoreWeave, Equinix Metal, NVIDIA DGX vMetal for lifecycle management, automated cluster setup, OS health
Fine-Tuning Bursty workloads, rapid environment creation/teardown, strong tenant isolation DigitalOcean, Equinix Metal, OVHcloud vMetal + vCluster Platform — spin up isolated tenant clusters per job or customer in seconds
Inference Low latency, high uptime, GPU sharing (MIG), autoscaling, tenant isolation Geographically distributed bare metal vMetal Auto Nodes for autoscaling + vCluster for control plane isolation + vNode (private beta) for kernel-native workload isolation

A few notes on the inference row: AI inference is projected to grow at a 35% compound annual rate and will likely represent over half of all AI compute by 2030. Yet According to industry reports, average GPU utilization in enterprises sits at just 5%, with well-orchestrated environments reaching 37%. The gap between those numbers is the business case for investing in a proper bare metal GPU provisioning and orchestration platform rather than over-provisioning hardware to compensate for inefficient scheduling.

For inference specifically, the vCluster Platform's isolation spectrum — shared nodes through dedicated nodes with vNode kernel isolation — lets you safely run multiple inference models on shared GPU hardware. You capture utilization gains without the security risk of running multiple tenants without proper isolation, and without the performance penalty of running everything in VMs.

The Layer That Determines Time-to-Revenue

Every platform on this list offers genuine value. CoreWeave gives you the best GPU hardware with managed Kubernetes on top. DigitalOcean gives you a trusted brand and single-tenant access to serious compute. Equinix Metal gives you a global footprint. Lambda gives researchers a frictionless on-ramp. OVHcloud gives you competitive pricing at scale.

But hardware is a commodity. The engineers who've been through the frustration of managing large bare metal clusters know that the management overhead — the OS upgrades, the node failures, the tenant isolation edge cases, the network configs that work until they don't — is where projects stall and budgets blow out.

The platforms that close the Metal-to-Model gap fast are the ones that treat provisioning, orchestration, and isolation as a unified software stack rather than a collection of loosely integrated tools. That's the architectural bet vMetal makes, and it's why customers like Lintasarta could launch a production GPU cloud in 90 days instead of 18 months.

If you're building an AI cloud — whether that's a commercial neocloud, an inference-as-a-service product, or an internal AI factory for a large enterprise — the provisioning layer isn't a detail you figure out after the hardware arrives. It's the decision that sets your operational ceiling.

Frequently Asked Questions

What is bare metal GPU provisioning?

Bare metal GPU provisioning is the process of automating the setup of physical servers with GPUs, from initial hardware discovery to a fully configured, production-ready state. This includes OS installation, driver configuration, networking setup, and integration into a cluster management system like Kubernetes.

Why is automating bare metal GPU provisioning so important for AI clouds?

Automating bare metal GPU provisioning is crucial because it dramatically reduces the time and manual effort required to turn racked servers into revenue-generating resources. Manual processes are slow, error-prone, and don't scale, creating a significant bottleneck that delays time-to-market and increases operational costs for AI cloud providers.

What is the "Metal-to-Model gap"?

The "Metal-to-Model gap" refers to all the complex software and configuration steps required to transform raw, racked physical servers (metal) into a functional platform with strong tenant isolation, capable of running AI workloads (models). Closing this gap involves automating hardware provisioning, Kubernetes orchestration, networking, and tenant isolation, which is the primary function of platforms like vMetal.

How do full-stack provisioning platforms like vMetal differ from IaaS providers like CoreWeave or DigitalOcean?

A full-stack provisioning platform like vMetal is software you run on your own hardware, wherever it's located, giving you control over your infrastructure. IaaS providers like CoreWeave or DigitalOcean offer a managed service where you rent access to their pre-configured hardware, meaning you are deploying on their cloud, not building your own.

What is tenant isolation and why is it critical for GPU clouds serving multiple tenants?

Tenant isolation is the practice of securely separating the workloads and data of different customers (tenants) running on shared physical hardware. It is critical for security, preventing one tenant from accessing another's data, and for performance, ensuring one tenant's workload doesn't negatively impact another's by monopolizing resources.

Can I use a provisioning platform on my existing hardware or with any provider?

Yes, a key benefit of a hardware-agnostic provisioning platform like vMetal is that it can be deployed on top of any physical hardware you own or lease. This gives you the flexibility to use existing servers, switch between bare metal providers like Equinix Metal or OVHcloud, or build a hybrid fleet without being locked into a single vendor's ecosystem.

How does the choice of provisioning platform affect AI workload performance for training vs. inference?

The right provisioning platform optimizes for the specific needs of different AI workloads. For large-scale training, it ensures stable, long-running clusters with high-speed networking. For inference, it enables low-latency performance, rapid autoscaling of GPU resources, and efficient GPU sharing through strong tenant isolation, maximizing utilization and reducing costs.
