Pros & Cons

Hot Aisle

Advantages

Considerations

Single public region (Grand Rapids, MI) limits locality options
AMD-only GPU lineup today; MI355X is reservation-only for now
Self-service VMs top out at 4 GPUs; 8-GPU nodes require a bare metal reservation with a one-month minimum

OpenRelay

Advantages

Global infrastructure for increased availability
Support for multiple AI models
Comprehensive documentation and API resources
Flexible resource management

Considerations

Limited information on company ownership
Headquarters location not specified
