     <Description>Azure Data Factory V2 is the data integration platform that goes beyond Azure Data Factory V1's orchestration and batch-processing of time-series data, with a general purpose app model supporting modern data warehousing patterns and scenarios, lift-and-shift SSIS, and data-driven SaaS applications. Compose and manage reliable and secure data integration workflows at scale. Use native ADF data connectors and Integration Runtimes to move and transform cloud and on-premises data that can be unstructured, semi-structured, and structured with Hadoop, Azure Data Lake, Spark, SQL Server, Cosmos DB and many other data platforms.</Description>
