Per-cloud Notes

AWS

  • p4d / p4de / p5 / p5e instance types.
  • EFA + libfabric best-effort (rely on TCP retransmit eBPF).
  • IAM auth via SPIFFE trust.

GCP

  • a3-highgpu / a3-megagpu.
  • VPC-native + multi-NIC, IB is exposed via NCCL.

Azure

  • ND H100 v5.
  • NDm A100 v4.
  • Accelerated networking via MANA.

OCI / Lambda

  • BM.GPU.H100.8 / H200.8.
  • Best effort.

on-prem

  • The control plane supports air-gapped install on bare metal.
  • HSM-rooted KMS via PKCS#11.

Kubernetes Operators on Cloud

We integrate with:

  • Karpenter (AWS / GCP)
  • Cluster Autoscaler (legacy)
  • Volcano (on-prem)
  • KubeRay (all)

Test Coverage

Each cloud provider ships an integration test that uses a 4-GPU spot instance + a CP-VM in the same VPC to verify the round trip.
