You now understand the major cloud data warehouse options:
- Snowflake's -layer architecture separates storage, compute, and services
- Databricks offers a lakehouse combining lake flexibility with warehouse performance
- Delta Lake adds ACID transactions to data lakes
- BigQuery is serverless; Redshift is cluster-based
In interviews, be ready to explain tradeoffs. "It depends" is acceptable if you explain what it depends on: cost model, existing cloud provider, ML needs, data sharing requirements.
