# Cloud DNS costs

> Compare Cloud DNS backend choices using explicit service-adapter planning assumptions.

Tensor9 BYOC planning comparisons for `google::1.0.0::dns`, with backend choices shown together. Read [how Tensor9 estimates service-adapter costs](/byoc/costs/overview.md) for price scope and capacity qualification, or return to [additional services](/byoc/costs/additional-services.md).

## Authoritative DNS zones and queries (Cloud DNS) → Azure DNS

Origin API: `google::1.0.0::dns`. Target backend: `azure::1.0.0::dns`.

**Designed mapping.** This cost model describes an intended adapter. Its estimated price does not establish a delivered or selectable backend.

### Authoritative DNS zones and queries (Cloud DNS) · Authoritative DNS queries per second

Estimated monthly service charges by Authoritative DNS queries per second. Adapter hosting and Tensor9 fees are excluded. Source: us-central1; target: eastus; currency: USD.

Comparison pills describe all sampled scale points; card amounts show the named workload. Costs The Same means within 20% at every point. Costs Depend includes mixed results and unpriced samples.

Exact sampled model outputs in USD/month. Difference means target minus origin; a positive difference means the target costs more.
