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

Here are several bare-metal GPU platforms that combine dedicated, single-tenant hardware with the governance controls (policy-based access, metering, compliance certifications, isolation) needed for secure AI training:

1. CoreWeave – Offers
secure, single-tenant bare-metal clusters that enable isolated environments
, and its confidential GPU cloud
provides tailored GPU solutions that support HIPAA compliance, specializing in the healthcare and finance sectors, with secure GPU access, encrypted memory, and strong monitoring and logging
. corvex.ai

2. Lambda Cloud –
Offers bare-metal and virtual GPU servers tailored for AI research and production, with enterprise offerings including clusters with NVIDIA A100s and H100s
. runpod.io

3. IBM Cloud Bare Metal –
Offers enterprise-grade bare metal servers with a range of NVIDIA GPUs, RDMA cluster networking for ultra-low latency, and a secure, enterprise-focused cloud environment with strong compliance certifications (GDPR, HIPAA, SOC)

For the "governance layer" itself (self-service provisioning with metering/RBAC on top of bare metal), platforms like NorthWind are built specifically to add
elastic, self-service provisioning of bare metal GPU servers with governance, visibility, and metering built in
for enterprises deploying their own GPU infrastructure. northwind.co
