Enterprise Lakehouse & Data Architecture
A governed Azure Databricks lakehouse with Bronze/Silver/Gold layers, metadata-driven onboarding, automated data quality, and CI/CD — built for many teams and many sources.
Enterprise data platform · Azure & Databricks
Problem
Operational data from many systems had to be onboarded quickly and consistently, governed centrally, and trusted by downstream consumers — without every new source becoming a bespoke pipeline.
Architecture
- 01Bronze, Silver, and Gold medallion layers on Delta Lake separate raw, conformed, and business-ready data.
- 02Unity Catalog provides central governance, access control, and lineage.
- 03A metadata-driven framework handles onboarding, orchestration, audit, and operational patterns for new sources.
- 04An enterprise data quality framework runs automated, metadata-defined validation and exception handling.
- 05A reusable API integration framework securely ingests REST endpoints from operational systems.
- 06Azure DevOps CI/CD promotes code and configuration across environments.
Engineering decisions
- Configuration over code for onboarding
- New sources are described in metadata and run through shared, tested pipelines instead of hand-written jobs.
- Quality rules as data
- Validation rules are stored as metadata so they can scale to thousands of business rules and be reviewed without code changes.
- Governance from day one
- Unity Catalog permissions, lineage, and auditing are part of the platform foundation rather than added later.
- DevOps for data
- Standardized CI/CD, environment promotion, monitoring, and recovery procedures make the platform reliable to operate.
Technologies

- Azure Databricks
- Delta Lake
- Unity Catalog
- Auto Loader
- Lakeflow
- Azure Data Factory
- Azure DevOps
Outcomes
- Consistent, repeatable onboarding across diverse data sources.
- Automated validation and exception controls across thousands of business rules.
- Standardized CI/CD, access control, monitoring, and recovery across environments.
Lessons learned
- The second pipeline is where frameworks pay off — design for the hundredth source early.
- Data quality is a product feature; make failures visible to the people who own the data.
- Bringing DevOps discipline to Databricks is as much about process as it is about tooling.
