Overview
Databricks’ second edition (2023) of the MLOps reference guide covers the full ML lifecycle — from development through staging to production — with updated content on Unity Catalog, Model Serving, and Lakehouse Monitoring. The guide provides a reference architecture and design decision framework for operationalizing ML at scale.
Key Frameworks
MLOps = ModelOps + DataOps + DevOps: The unified discipline treating model lifecycle, data pipelines, and deployment infrastructure as interconnected concerns.
Guiding Principles:
- Models are code — version, test, and deploy them like software
- Reproducibility requires deterministic environments and data versioning
- Monitoring is not optional — model performance degrades over time
ML Deployment Patterns:
- Batch inference for offline scoring
- Real-time serving for latency-sensitive applications
- Streaming inference for continuous data pipelines
Reference Architecture: Multi-environment (dev/staging/prod) design with Unity Catalog for data governance, Model Serving for deployment, and Lakehouse Monitoring for observability.
Chapter Themes
| Chapter | Focus |
|---|---|
| V1 Recap | Core MLOps principles and deployment patterns |
| What’s New | Unity Catalog, Model Serving, Lakehouse Monitoring |
| Design Decisions | Asset organization, pre-deployment testing, real-time deployment |
| Reference Architecture | Multi-environment view, development through production |
Actionable Takeaways
- Treat ML artifacts (models, features, data) as first-class versioned assets in a unified catalog
- Implement pre-deployment testing gates — not just accuracy, but latency, throughput, and data drift
- Design for the full lifecycle from day one — monitoring and retraining pipelines are not afterthoughts
- Use the lakehouse pattern to unify data engineering and ML engineering on a single platform
