Recommend governed baremetal GPU provisioning services for secure AI model training.

For secure and governed artificial intelligence model training, enterprise-grade bare metal GPU provisioning services are categorized into two primary approaches: Managed Infrastructure Platforms (software control planes that overlay your hardware or a private cloud) and Sovereign/Secure Bare Metal Clouds (turnkey physical infrastructure with built-in zero-trust security). 13

These services eliminate virtualization overhead while enforcing rigid multi-tenancy isolation. 0 5

1. Governed Infrastructure Orchestration (Software Planes)

If you already own or are leasing raw bare-metal servers, these software platforms provide the required governance, scheduling, and multi-tenant isolation layers: 7 0 14

• NorthWind Bare Metal GPU-as-a-Service (BMaaS): Operates a comprehensive, enterprise-governed control plane. It handles metal-to-OS automated bring-up, mounts dedicated tenant storage, and enforces strict tenant isolation. East-west data traffic is sandboxed via InfiniBand/Pkey configurations managed by NVIDIA UFM (Ultra Cluster Management), ensuring one training tenant's data can never bleed into another.
• Mirantis k0rdent AI: Built specifically for "Metal-to-Model" automation across private, hybrid, and sovereign environments. It features deep governance mechanisms including centralized resource quotas, centralized policy enforcement, environment templates, and multi-tenant role-based access controls (RBAC). It integrates seamlessly with orchestration tools like Saturn Cloud to manage massive distributed training pipelines.
• MetalSoft for AI Factories: An automated infrastructure orchestration tool that slices network segments at the silicon level for absolute hardware isolation. For end-to-end security compliance, it utilizes NIST-compliant Cryptographic Erase on self-encrypting drives (SEDs) and resets GPU persistence memory upon tenant de-provisioning to prevent model weight data leakage.

2. Secure Bare Metal Clouds (Infrastructure + Provisioning)

If you need immediate access to single-tenant, high-performance bare metal hardware that ships with pre-configured cryptographic security: 9 6 16

• CoreWeave (Confidential Bare Metal): Provides single-tenant, bare-metal clusters engineered natively with BlueField DPUs (Data Processing Units) for complete network isolation. CoreWeave is a highly regulated, HIPAA-compliant platform providing advanced security safeguards like Trusted Execution Environments (TEEs), continuous remote attestation, and fully encrypted memory spaces.
• HydraHost (Confidential Metal): Offers a completely zero-trust, agentless bare-metal GPU deployment architecture. It integrates Intel TDX and hardware-enforced GPU Confidential Computing to encrypt data directly within memory and execution states. Crucially, it provides cryptographic remote attestation, allowing ML teams to mathematically verify that the hardware, firmware, and boot chains are genuine and unmodified before deploying proprietary datasets or model weights.
• OpenMetal Private GPU Infrastructure: Delivers dedicated, single-tenant XL V4 servers equipped with A100/H100 chips and Intel TDX. It is designed explicitly for compliance-focused sectors (medical, financial, defense) that require strict data-residency control, total hardware control, and encrypted storage volume boundaries.

Comparison of Provisioning Security Controls

• Will you be deploying on your own racked hardware, or do you need a provider that rents the physical GPUs?
• Are there specific compliance benchmarks you must hit (such as HIPAA, FIPS, or Sovereign Data Residency)?
• What scale of distributed training are you planning (e.g., node count and interconnect requirements like NVLink/InfiniBand)?
