Concepts
Zero egress
Zero ingress, zero egress, zero inter-pod transfer — across every SKU.
Volt enforces zero ingress, zero egress, and zero inter-pod transfer across Spark, Forge, and Vault. This is a structural property, not a contract clause.
What it means
- No bandwidth fees, ever. Hyperscalers charge $0.05–0.09/GB egress; Volt charges nothing.
- Your data never leaves the pod it lands in. Sovereignty by physical placement, not by policy.
- Per-metro residency is a property of where the request was served.
How it's enforced
Three layers, each independent:
- SPIRE workload identity gates all cross-pod traffic — nothing talks to anything without a verified SVID.
- Cilium network policy at L3/L4 enforces a default-deny egress posture on every pod.
- Scheduler placement bakes pod-level network boundaries into where workloads run.
Why it matters
- Pricing: removes a whole category of hidden cost and simplifies quotes.
- Compliance: data residency is verifiable, which simplifies FedRAMP, the EU AI Act, and sector regulations.
- Trust: combined with client-side enforcement in the SDK, you get defense in depth.
The Volt SDK validates each response against your configured tier and metro. On a mismatch it raises and withholds the payload from your code — the third leg of the zero-egress design.
