The pre-requisites of this article are you need to be familiar with SQL Server, and SQL Server Integration Services (SSIS).
After deploying the package to SSIS IR, https://chanmingman.wordpress.com/2018/05/09/ssis-deploy-a-project-to-azure-ssis-integration-runtimes/, you might be facing another challenge. In SQL Server on premise you have SQL Jobs Agent that can execute multiple SSIS packages. Below is the sample of SQL Jobs.
When you open a job, click on the Steps, then you can see the SSIS packages that will be executed by the SQL Job.
For SSIS IR, sign in to Azure Portal then go to Data Factory. Create one if you do not have one.
Click on Author and Monitor.
Make sure you have created an Integration Runtimes, in this example, the name of the Integration Runtimes is simply IntegrationRuntimes1. Click this Run button.
Go back to your Pipelines, create one if it does not exist. My example here is ssisPM. Expand the General node then you will see Execute SSIS Package.
Drag Execute SSIS Package to the design pane.
Configure the SSIS package.
To test the pipeline, go to Add trigger then select Trigger Now.
Click on the Monitor to check whether the pipeline execute successfully.
