## Cost Scaling Factors
<a name="cost-scaling-factors"></a>

 **Vehicle telemetry and EV operations** (`vehicle_telemetry_aggregated`, `charging_sessions`, `energy_usage`, `ota_campaigns`):
+ Data volume: Costs scale with connected-vehicle fleet size
+ Query frequency: More Athena queries = higher costs

 **Customer data** (`customer_360`, `customer_interactions`):
+ Data volume: Costs scale linearly with customer count
+ Query frequency: More Athena queries = higher costs
+ Downstream consumers can subscribe via DataZone V2 for BI or analytics workloads

 **Predictive Maintenance**:
+ Fleet size: Larger fleets require more Glue and SageMaker Studio notebook capacity
