Pros & Cons

Hot Aisle

Advantages

Self-service MI300X VMs with transparent published rates metered by the minute, no sales call required
Dense XE9680 nodes with 8x400G RoCEv2 for multi-server scaling
Credit card to running compute in under a minute, with public IP and firewall control included
100G internet with unlimited bandwidth plus included IPv4/IPv6 addresses

Considerations

Single public region (Grand Rapids, MI) limits locality options
AMD-only GPU lineup today; MI355X is reservation-only for now
VMs top out at 4 GPUs; 8-GPU configurations are offered only as dedicated bare metal

Voltage Park

Advantages

Great GPU availability for on-demand use
No separate ingress, egress, or support charges
Fast deployment (spin up nodes in 15 minutes)
Bare metal access for maximum performance

Considerations

U.S.-only regions (limited global presence)
Low GPU variety (primarily H100s)
Relatively new provider (founded 2023)
