Lift and shift SQL Server Integration Services workloads to the cloud
You can now move your SQL Server Integration Services (SSIS) packages and workloads to the Azure cloud.
- Store and manage SSIS projects and packages in the SSIS Catalog database (SSISDB) on Azure SQL Database or SQL Database Managed Instance (Preview).
- Run packages in an instance of the Azure-SSIS Integration Runtime, a component of Azure Data Factory.
- Use familiar tools such as SQL Server Management Studio (SSMS) for common tasks.
Moving your on-premises SSIS workloads to Azure has the following potential benefits:
- Reduce operational costs and reduce the burden of managing infrastructure that you have when you run SSIS on-premises or on Azure virtual machines.
- Increase high availability with the ability to specify multiple nodes per cluster, as well as the high availability features of Azure and of Azure SQL Database.
- Increase scalability with the ability to specify multiple cores per node (scale up) and multiple nodes per cluster (scale out).
The following table highlights the differences between SSIS on premises and SSIS on Azure. The most significant difference is the separation of storage from runtime. Azure Data Factory hosts the runtime engine for SSIS packages on Azure. The runtime engine is called the Azure-SSIS Integration Runtime (Azure-SSIS IR). For more info, see Azure-SSIS Integration Runtime.

Custom solutions (in prior versions of SQL Server)
|On Azure (SQL Database or SQL Database Managed Instance (Preview))||Azure-SSIS Integration Runtime, a component of Azure Data Factory||Scaling options for the Azure-SSIS Integration Runtime|
You only have to provision the Azure-SSIS IR one time. After that, you can use familiar tools such as SQL Server Data Tools (SSDT) and SQL Server Management Studio (SSMS) to deploy, configure, run, monitor, schedule, and manage packages.
You can deploy a package created with any version of SSIS to Azure. When you deploy a package to Azure, if there are no validation errors, the package is automatically upgraded to the latest package format. In other words, it is always upgraded to the latest version of SSIS.
The deployment process validates packages to ensure that they can run on the Azure-SSIS Integration Runtime. For more info, see Validate SSIS packages deployed to Azure.
To deploy SSIS packages to Azure, you have to have one of the following versions of SQL Server Data Tools (SSDT):
- For Visual Studio 2017, version 15.3 or later.
- For Visual Studio 2015, version 17.2 or later.
For info about the prerequisites for the Azure-SSIS Integration Runtime, see Deploy SQL Server Integration Services packages to Azure - Prerequisites.
During this public preview, the Azure-SSIS Integration Runtime is not yet available in all regions. For info about the supported regions, see Products available by region - Microsoft Azure.
Provision SSIS on Azure
Before you can deploy and run SSIS packages in Azure, you have to provision the SSIS Catalog database (SSISDB) and the Azure-SSIS Integration Runtime. Follow the provisioning steps in this article: Deploy SQL Server Integration Services packages to Azure.
When you provision the Azure-SSIS IR, you can scale up and scale out by specifying values for the following options:
- The node size (including the number of cores) and the number of nodes in the cluster.
- The existing instance of Azure SQL Database to host the SSIS Catalog Database (SSISDB), and the service tier for the database.
- The maximum parallel executions per node.
For more info about performance, see Configure the Azure-SSIS Integration Runtime for high performance.
You continue to design and build packages on-premises in SSDT, or in Visual Studio with SSDT installed.
Connect to data sources
For info about how to connect to on-premises data sources from the cloud with Windows authentication, see Connect to on-premises data sources and Azure file shares with Windows Authentication.
For info about how to connect to files and file shares, see Store and retrieve files on file shares on premises and in Azure with SSIS.
Available SSIS components
When you provision an instance of SQL Database to host SSISDB, the Azure Feature Pack for SSIS and the Access Redistributable are also installed. These components provide connectivity to various Azure data sources and to Excel and Access files, in addition to the data sources supported by the built-in components.
You can also install additional components. For more info, see Custom setup for the Azure-SSIS integration runtime.
If you're an ISV, you can update the installation of your licensed components to make them available on Azure. For more info, see Develop paid or licensed custom components for the Azure-SSIS integration runtime.
With SQL Server on premises and on Azure virtual machines, you can use Microsoft Distributed Transaction Coordinator (MSDTC) transactions. To configure MSDTC on each node of the Azure-SSIS IR, use the custom setup capability. For more info, see Custom setup for the Azure-SSIS integration runtime.
With Azure SQL Database, you can only use elastic transactions. For more info, see Distributed transactions across cloud databases.
Deploy and run packages
Deployment model. You have to use the project deployment model, not the package deployment model, when you deploy projects to SSISDB on Azure.
Deployment and execution options. To deploy projects and run packages on Azure, you can use one of several familiar tools and scripting options:
- SQL Server Management Studio (SSMS)
- Transact-SQL (from SSMS, Visual Studio Code, or another tool)
- A command-line tool
- C# and the SSIS management object model
Connect to SSISDB. The name of the SQL Database that hosts SSISDB becomes the first part of the four-part name to use when you deploy and run packages from SSDT and SSMS, in the following format -
<sql_database_name>.database.windows.net. For info about how to connect to the SSIS Catalog database in Azure, see Connect to the SSISDB Catalog database on Azure.
To get started, see Deploy, run, and monitor an SSIS package on Azure.
To monitor running packages in SSMS, you can use the following reporting tools in SSMS.
- Right-click SSISDB, and then select Active Operations to open the Active Operations dialog box.
- Select a package in Object Explorer, right-click and select Reports, then Standard Reports, then All Executions.
To monitor the Azure-SSIS Integration Runtime, see Monitor the Azure-SSIS integration runtime.
To schedule the execution of packages stored in Azure SQL Database, you can use a variety of tools. For more info, see Schedule SSIS package execution on Azure.
