Azure Blob Egress Connector

Version: 17.07

Supported Since: 17.07

What is an Azure Blob Egress Connector?

Azure Blob Egress Connector can be used to push files to an Azure Blob container.

When sending messages to a blob container, UltraESB engine expects the file content as the message payload and file name as a variable. However, this connector can be configured to override the file name of the original file with an arbitrary file name.

Azure credentials associated with an account which has write permission to the target container will be necessary when configuring this connector.
In order to use the Azure Blob Egress Connector, you must first select the Azure Connector dependency from the connector list when you are creating an empty Ultra project. If you have already created a project, you can add the Azure Connector dependency via Component Registry. From Tools menu, select Ultra Studio → Component Registry and from the Connectors list, select the Azure connector dependency.
