Access to Azure Virtual Network resources from Azure Logic Apps by using integration service environments (ISEs)
This capability is in public preview.
Sometimes, your logic apps and integration accounts need access to secured resources, such as virtual machines (VMs) and other systems or services, in an Azure virtual network. To set up this access, you can create an integration service environment (ISE) for running your logic apps and integration accounts. When you create an ISE, Azure deploys a private and isolated instance of the Logic Apps service into your Azure virtual network. This private instance uses dedicated resources such as storage, and runs separately from the public "global" Logic Apps service. Separating your isolated private instance and the public global instance also helps reduce the impact that other Azure tenants might have on your apps' performance, which is also known as the "noisy neighbors" effect.
After creating your ISE, when you go to create your logic app or integration account, you can select your ISE as your logic app or integration account's location:
Your logic app can now directly access systems that are inside or connected to your virtual network by using any of these items:
- An ISE-versioned connector for that system, for example, SQL Server
- A built-in trigger or action, such as the HTTP trigger or action
- A custom connector
This overview describes more details about how an ISE gives your logic apps and integration accounts direct access to your Azure virtual network and compares differences between an ISE and the global Logic Apps service. For on-premises systems that aren't connected to a virtual network or don't have ISE-version connectors, you can connect to those systems by setting up and using the on-premises data gateway.
Logic apps, built-in actions, and connectors that run in your ISE use a different pricing plan, not the consumption-based pricing plan. For more information, see Logic Apps pricing.
Isolated versus global
When you create an integrated service environment (ISE) in Azure, you can select the Azure virtual network where you want to inject your ISE. Azure then injects, or deploys, a private instance of the Logic Apps service into your virtual network. This action creates an isolated environment where you can create and run your logic apps on dedicated resources. When you create your logic app, you select your ISE as your app's location, which gives your logic app direct access to your virtual network and the resources in that network.
Logic apps in an ISE provide the same user experiences and similar capabilities as the global Logic Apps service. Not only can you use the same built-in actions and connectors in the global Logic Apps service, but you can also use ISE-specific connectors. For example, here's some standard connectors that offer versions that run in an ISE:
- Azure Blob Storage, File Storage, and Table Storage
- Azure Queues, Azure Service Bus, Azure Event Hubs, and IBM MQ
- FTP and SFTP-SSH
- SQL Server, SQL Data Warehouse, Azure Cosmos DB
- AS2, X12, and EDIFACT
The difference between ISE and non-ISE connectors is in the locations where the triggers and actions run:
In your ISE, built-in triggers and actions such as HTTP always run in the same ISE as your logic app.
For connectors that offer two versions, one version runs in an ISE, while the other version runs in the global Logic Apps service.
Connectors that have the ISE label always run in the same ISE as your logic app. Connectors without the ISE label run in the global Logic Apps service.
Connectors that run in an ISE are also available in the global Logic Apps service.
Integration accounts with ISE
You can use integration accounts with logic apps inside an integration service environment (ISE). However, those integration accounts must use the same ISE as the linked logic apps. Logic apps in an ISE can reference only those integration accounts that are in the same ISE. When you create an integration account, you can select your ISE as the location for your integration account.
