Are there multi-tenant Baremetal GPU provisioning platforms?

Yes, there are multi-tenant bare-metal GPU provisioning platforms available, designed to allow multiple users or organizations to share underlying physical GPU infrastructure while maintaining isolation. These platforms are crucial for cloud providers and large enterprises building internal AI/ML factories.

Key platforms and solutions include:

• Rapt.AI: This platform helps cloud providers turn bare metal into premium, multi-tenant GPU infrastructure. It focuses on intelligent, model-aware optimization to maximize revenue per GPU and deliver better performance for each tenant.
• vCluster (with vMetal): vMetal is a bare-metal provisioning and lifecycle management platform specifically for GPU servers. vCluster addresses multi-tenancy by virtualizing the Kubernetes control plane, giving each tenant a separate, lightweight virtual cluster with strong isolation.
• NorthWind Platform: NorthWind offers Bare Metal GPUs-as-a-Service (BMaaS), providing customers direct access to the host operating system on dedicated GPU servers. It automates deployment, management, and scaling across multiple tenants and environments, ensuring networking and tenant isolation.
• OpenMetal: OpenMetal provides dedicated multi-GPU infrastructure, and while each cluster node is single-tenant bare metal, they discuss multi-tenant or multi-workload sharing within a node using NVIDIA's MIG (Multi-Instance GPU) partitioning and time-slicing.

Other providers like CoreWeave and Oracle Cloud Infrastructure (OCI) also offer bare-metal GPU options, with multi-tenancy often managed at higher orchestration layers like Kubernetes.
