Key Architectural Takeaways
Managed Private Endpoints secure outbound Spark and Data Factory connections to backend databases.
Azure Private Link prevents public internet exposure of the Fabric portal.
Cluster on-premises data gateways in active-active HA configurations.
Verify private DNS zone resolution across hybrid on-prem and cloud boundaries.
01
VNet Injection & Private Endpoint Topology
Protect Fabric compute engines and storage against public internet exposure. Configure Managed Private Endpoints from Fabric workspaces to backend Azure SQL, ADLS Gen2, and Snowflake resources. Enable Azure Private Link for inbound client connections to Fabric tenant workspaces.
Implementation & Verification Checklist
4 Verification Checks- Document complete network data paths from source on-prem databases to OneLake
- Provision Managed Private Endpoints for secure outbound connections from Fabric Spark & Data Factory
- Configure Azure Private Link for inbound corporate network traffic to Fabric portal
- Verify private DNS zone resolution across hybrid network boundaries
02
On-Premises Data Gateway High Availability
When ingesting data from on-premises SQL Server, Oracle, or SAP sources, deploy On-Premises Data Gateway clusters in High-Availability (HA) load-balanced configurations. Monitor gateway CPU, memory, outbound TCP port connectivity, and failover behavior under peak ETL batch windows.
Implementation & Verification Checklist
4 Verification Checks- Cluster minimum 2 gateway nodes for active-active load balancing and redundancy
- Validate outbound TCP port 443 connectivity to Fabric service endpoints
- Perform automated failover testing by taking primary gateway node offline during ingestion
- Monitor gateway network throughput and queue latency in Azure Monitor
