D Docket
Azure FinOps

Turn Azure cost data into action, at the speed you actually need it.

Docket combines daily billing exports, near-real-time AI usage telemetry, and AI-generated optimization recommendations into one place — with a resource management layer that can act on what it finds.

Three latency tiers, one picture of cost

Each tier trades latency for depth — realtime metrics for "what's happening now," daily exports for "what we're actually being billed."

Tier 1 · ~1 min

Realtime metrics

Azure Monitor metrics surfaced directly in Grafana — no extra infrastructure required.

Tier 2 · 1–5 min

Near-realtime AI usage

Azure OpenAI diagnostic logs stream through Event Hub into a cost estimator, priced per request as it happens.

Tier 3 · 4–24h

Daily billed costs

FOCUS-format Cost Management exports land daily for the numbers that reconcile against the actual invoice.

AI Advisor

Weekly recommendations

An LLM reviews the accumulated cost data on a weekly cadence and produces ranked optimization suggestions.

Cost Centre API

Adoption & lifecycle

Tracks which teams and cost centres are onboarded, and exposes the data the other tiers depend on.

Built on

Provisioned end-to-end with Terraform; no manually-created resources.
