Study Notes
Managed Identity in Azure Data Factory
- Managed identities eliminate the need to manage credentials and provide an identity for the service instance when connecting to resources that support Microsoft Entra authentication.
- Managed identities allow access to resources like Azure Key Vault and storage accounts, where data admins can securely store credentials.
Types of Managed Identities
- There are two types of supported managed identities: system-assigned and user-assigned.
- System-assigned managed identity is generated automatically when requested, and user-assigned managed identity is created, deleted, and managed in Microsoft Entra ID.
Generating System-Assigned Managed Identity
- System-assigned managed identity can be generated using PowerShell, REST API, or SDK.
- The "identity" section is populated accordingly after generating a system-assigned managed identity.
- Example code for generating system-assigned managed identity using .NET:
FactoryIdentity().
Retrieving System-Assigned Managed Identity
- Managed identity information can be found in the Azure portal -> your data factory -> Properties.
- The managed identity principal ID and tenant ID will be returned when getting a specific service instance using PowerShell or REST API.
- The PrincipalId can be used to grant access, and the application ID can be obtained by copying the principal ID and running a Microsoft Entra ID command.
