Are you curious about how Azure Data Factory (ADF) efficiently handles massive data movement across diverse environments—both cloud and on-premises?

Control & Orchestration

ADF pipelines are controlled centrally with built-in scheduling and orchestration. This allows flexible control flow using features like concurrency and partitioning to scale out data flows efficiently.

Integration Runtime (IR)

ADF uses two types of IRs to move your data:
Azure IR Managed by Microsoft, ideal for:

  • Cloud data movement

  • Azure-to-Azure copy

  • Auto-scaling infrastructure using Data Integration Units (DIUs)

Self-hosted IR – Managed by you, best for

  • On-premises data movement (e.g., SQL Server, Oracle, Teradata)

  • Custom environments with high concurrency and scalability

Data Movement Across Environments

  • ADF supports Cloud Data Stores (e.g., Amazon S3, Salesforce, Azure Blob)
    and On-prem Data Stores (e.g., SAP, SQL Server, Oracle)

  • All integrated seamlessly through IRs to Azure Data Stores like Azure SQL, Synapse, Cosmos DB, and more.

With ADF, you get:

  • Elastic scaling for large data volumes

Smart resource usage via configurable DIUs

💡
Whether you're modernizing ETL or building a data lake, ADF copy activity can scale to meet your needs.
