$ ./needs — size the supernet from the bottom up

Describe the infrastructure you actually need. The pipeline walks AZ → VPC → env → region → supernet using power-of-two CIDR math — the block you can really allocate, not a packed fantasy.

Workload subnet mask

/24

AZs per VPC

VPC mask

/22

Must be a larger network than the subnet (smaller number)

VPCs per environment

Environments (incl. platform/shared)

Regions

Interconnection

VPC Peering Transit Gateway

ALIGNED (allocate this)

—

RAW PACK (fantasy minimum)

Next step

Build a skeleton region/env/VPC tree in the spatial calculator, pre-sized to this supernet.

$ ./needs — size the supernet from the bottom up

// why aligned ≠ packed
