This is where platform success is decided.

🔹 Why Chargeback Matters

Without chargeback:

• Teams treat compute as free

• Query discipline collapses

• Platform team blamed for cost

With chargeback:

• Behavior changes immediately

🔹 Chargeback Models

1️⃣ Query-Based

Each query:

• Tagged by team

• Slot-ms attributed

• Billed monthly

Transparent but noisy.

2️⃣ Reservation-Based

Each team:

• Gets dedicated slots

• Pays for commitment

• Manages own scaling

Very effective behaviorally.

3️⃣ Data Product Pricing

Teams pay per:

• TB stored

• TB scanned

• Feature computed

• API call served

Aligns cost to usage.

🔥 Behavior-Shifting Techniques

1. Show cost per dashboard view

2. Show cost per ML model

3. Show cost per experiment

4. Compare teams publicly (internally)

Nothing changes behavior like visible cost.

🔹 Ideal KPI Model

Each business unit sees:

Translate infrastructure → business value.

🧠 The Meta-Level View at 100PB

🔥 Final Executive Insight

At 100PB scale:

• Architecture prevents bad queries.

• Governance prevents bad economics.

• Chargeback prevents bad behavior.

• Control plane prevents chaos.

• Regionalization prevents regulatory risk.

• Precomputation prevents shuffle explosion.

• Cultural discipline prevents $100M mistakes.
