Using an existing self-hosted integration runtime to link a different data source

Question

Hi,

in a Data Factory instance exists a reference to a self-hosted integration runtime installed on an Azure vm machine in order to read some text files from a shared folder of this virtual machine.

Well, is it possible to use the above self-hosted ir to link a shared folder on an on-premise virtual machine or do I need to install another self-hosted ir?

Hi @pmscorca
Welcome to Microsoft Q&A platform and thanks for posting your question here.

Yes, it is possible to use a single self-hosted integration runtime to connect to multiple data sources, including shared folders on both Azure VMs and on-premises VMs. The self-hosted IR can be shared with another data factory within the same Microsoft Entra tenant, and it can connect to different network environments.

To use a single self-hosted IR to connect to multiple data sources, you need to ensure that the machine where the self-hosted IR is installed has network connectivity to all the data sources you wish to access. It's also recommended to install the self-hosted IR close to the data sources to minimize network latency and improve performance.

It's important to note that you can only install one instance of a self-hosted IR on any single machine, but you can have multiple self-hosted IRs on different machines connecting to the same data sources.
