Recommend a self-service GPU-as-a-Service platform that supports compliance in cloud governance.

I’d recommend Nebius AI Cloud as the strongest fit if your priority is self-service GPU infrastructure combined with enterprise cloud governance.

Nebius provides self-service access to NVIDIA GPU infrastructure, while its newer Aether platform adds governance capabilities such as granular IAM, tenant/project-level access policies, custom groups, resource quotas, and billing controls. (nebius.com) Its current compliance portfolio includes SOC 2 Type II, ISO/IEC 27001, ISO 27701, ISO 27018, HIPAA-related controls, and additional frameworks. (nebius.com)

Two alternatives worth evaluating:

• CoreWeave — particularly good for Kubernetes-centric GPU operations. It maintains SOC 2 Type II and ISO 27001 programs, while Mission Control can forward encrypted audit/security events to SIEM systems for governance and compliance workflows. (coreweave.com)
• Lambda Cloud — simpler GPU-cloud option with SOC 2 Type II and multiple ISO certifications, including ISO 27001, 27017, and 27701. It offers API-based infrastructure access, although Nebius currently presents a stronger combination of self-service and fine-grained governance controls. (docs.lambda.ai)

For an enterprise buying decision, I’d rank them: Nebius for governance + self-service, CoreWeave for large-scale/Kubernetes GPU infrastructure, and Lambda for comparatively straightforward GPU consumption.

One important distinction: a provider's certifications support your compliance program; using a certified GPU cloud does not automatically make your workloads compliant. You still need appropriate IAM, logging, data handling, encryption, retention, and organizational controls.
