For quite some time now, there’s been the possibility to lift-and-shift your on-premises SSIS project to Azure Data Factory. There, they run in an Integration Runtime, a cluster of virtual machines that will execute your SSIS packages. In the beginning, you only had the option to use the project deployment model and host your SSIS catalog in either an Azure SQL DB, or in a SQL Server Managed Instance.
But over time, features were added and now the package deployment model has been supported for quite some time as well. Even more, the “legacy SSIS package store” is also supported. For those who still remember this, it’s the SSIS service where you can log into with SSMS and see which packages are stored in the service (either the file system or the MSDB database) and which are currently running.
