About This Architecture

Azure-AWS cross-cloud Databricks LakeFlow architecture integrates Premium Databricks workspaces in Azure UK South with RDS MySQL and PostgreSQL databases in AWS eu-west-2 via Cato SASE backbone. Data flows from LakeFlow Classic and Serverless Compute through Azure Firewall and Cato Socket, traversing an IPsec tunnel to AWS RDS instances with CDC-driven Delta Lake ingestion into Unity Catalog volumes. This pattern solves multi-cloud data gravity challenges while enforcing network segmentation, encryption, and threat prevention across trust boundaries. Fork and customize this diagram on Diagrams.so to adapt subnet ranges, RDS instance types, or add additional cloud regions. The architecture demonstrates best practices for hybrid cloud data integration: VNet injection for Databricks, forced egress via firewall, and SASE-based secure connectivity eliminating VPN complexity.

How do I securely connect Azure Databricks to AWS RDS databases across regions using a multi-cloud architecture?

This diagram shows a complete Azure-AWS cross-cloud pattern: Azure Databricks Premium (VNet-injected in UK South) connects via Azure Firewall and Cato Socket to a Cato SASE backbone, which tunnels to AWS eu-west-2 RDS instances (MySQL and PostgreSQL). LakeFlow Classic and Serverless Compute run CDC pipelines that ingest data into Unity Catalog Delta tables, enforcing encryption, threat prevention,
