Updated May 8, 2026 A Virtual Private Cloud (VPC) on Raff is an isolated private network for VMs in the same region. VPCs are opt-in — create one when you want two or more VMs to talk to each other privately at near-line-rate without going over the public internet, or to put a fleet behind a single internet gateway. A VM that doesn’t join a VPC is still fully usable; it just reaches the internet through its public IP and has no private peer network. Under the hood, every VPC is a VXLAN segment with its own 24-bit VNI — that’s what makes them isolated, and why two VPCs can use the same CIDR and still never see each other.Documentation Index
