Inference meta-monitoring for Amazon SageMaker AI endpoints with Amazon Quick

This article introduces inference meta-monitoring for Amazon SageMaker AI endpoints, providing a governance layer to continuously track prediction and data quality metrics with drift detection and automated dashboards.

• Combines SageMaker AI, Athena Iceberg tables, Lambda, EventBridge, and Amazon Quick for end-to-end monitoring
• Detects data drift by comparing current inference distributions against frozen training baselines using statistical tests
• Detects model drift by comparing current predictions with ground truth against frozen evaluation baselines using classification metrics
• Uses Jensen-Shannon distance for normalized drift magnitude scoring, enabling cross-feature comparison on a unified 0-1 scale
• Provides pre-built Amazon Quick dashboards with 32 visuals tracking model drift trends, data drift trends, and feature-level drift rankings
• Integrates with SageMaker MLflow Apps for interactive Evidently reports and experiment tracking
• Implements ACID-compliant Iceberg tables for immutable baseline versioning tied to model package ARNs and code commits
• Costs approximately $60/month with serverless inference and on-demand compute scaling to zero when idle

The solution enables proactive governance by transforming reactive incident response into continuous monitoring, eliminating silent model degradation in production ML systems.
