What is Linked Service in Azure Data Factory

In this article we will discussed about Linked Service In Azure Data Factory.

Linked Service:

Linked services is like a connection string(s), defines the connection information for Data Factory to connect the external resources. A linked service defines the connection to the data source and a dataset that represents the structure of the data. Example - an Azure Storage linked service specifies connection string to connect to the Azure Storage account. And, an Azure Blob dataset specifies the blob container and the folder contains the data.

Linked services can be used for two purposes in Azure Data Factory:

  • To represent/show a data store including, but it doesn’t have any limited to on-premises SQL Server, Oracle database, file share, or an Azure Blob Storage account.
  • To represent a compute resource that can host the execution of an activity. Example, the HDInsightHive activity runs on an HDInsight Hadoop cluster. 


Create Linked Service using portal: 

Azure blog storage linked service:

    "name": "SourceAzureStorageLinkedService",
    "properties": {
        "description": "Source Linked Service create for the connect blob storage.",
        "type": "AzureStorage",
        "typeProperties": {
            "connectionString": "DefaultEndpointsProtocol=https;AccountName=ithubcity1;AccountKey=**********"
