Why it matters

For HPC, gaming, and other performance-sensitive workloads, OCI bare metal at OCI pricing can be dramatically cheaper than AWS/GCP equivalents.

The architecture

Shapes are the OCI equivalent of instance types. Standard, DenseIO, GPU, HPC, and A1 (ARM) families. Flexible shapes (VM.Standard.E4.Flex) let you pick exact vCPU and memory.

Bare metal shapes (BM.Standard) run without virtualization. You get the whole box.

How it works end to end

Boot volumes are automatically created from images. Block volumes attach separately for data.

Preemptible instances (like AWS Spot) offer discounts for interruptible workloads.

Instance pools + autoscaling for horizontal scaling.
