Multi-account AWS architecture isolates Databricks data plane in a customer-managed VPC while integrating with AWS Glue, Lake Formation, and Unity Catalog via PrivateLink. Account A hosts analytics services (Athena, EMR, Redshift, SageMaker) accessing Glue Data Catalog; Account B runs Databricks control and data planes with compute nodes in private subnets; Account C stores customer data in S3 with cross-account IAM trust and dual governance from Lake Formation and Unity Catalog. This zero-trust design eliminates public internet exposure while enabling Iceberg REST API federation between Glue and Unity Catalog metastores.
