The Integration Runtime in Azure Data Factory and Azure Synapse is the computing infrastructure that allows for integrating data from different network environments. It provides the bridge between activities and linked services. IR provides the following capabilities:
Data flow – Execute any Data flows.
Data movement – Copy data across stores in a public or private network.
Activity dispatch – Dispatch and monitor transformation activities on a variety of computing services.
SSIS packages execution – Execute SSIS packages in an Azure environment.
Types of IR
There are three types of IR:
Azure – Data flow, Data movement and Activity dispatch
Self-hosted – Data movement and Activity dispatch
Azure-SSIS – SSIS package execution
