This document discusses integrating MuleSoft with Microsoft Azure using the Mule ESB. It describes how the Microsoft Service Bus connector allows accessing Azure data and services. The steps shown include creating an Azure namespace, configuring the connector with access keys, and using flows to fetch queue lists from Azure storage.

Overview
- MuleSoft provides the most widely used integration platform to connect any application, data
service or API, across the cloud and on-premise continuum.
- Microsoft Azure is cloud-based data-storage infrastructure that is accessible to the user
programmatically via a MuleSoft ‘Microsoft Service Bus’ connector..
- The Microsoft Service Bus Mule connector allows developers to access any amount of data, at
any time, from anywhere on the web. With connectivity to the Microsoft Azure API, users can
interface Azure to store objects, download and use data with other Azure services, and build
applications that call for internet storage - all from within MuleSoft Anypoint Platform.

Prerequisites
• Microsoft Azure Account
• Microsoft Azure Namespace, Shared Access Key Name and Shared Access Key
• Mule Anypoint Microsoft Service Bus Connector
Microsoft Azure Account
To complete this sample, you need an Azure account. You can activate your MSDN subscriber
benefits or sign up for a free trial.

Creating Microsoft Azure Namespace
To begin using Service Bus topics and subscriptions in Azure, you must first create a service
namespace. A service namespace provides a scoping container for addressing Service Bus
resources within your application.
• Log on to the Azure Management Portal.
• In the left navigation pane of the Management Portal, click Service Bus.
• In the lower pane of the Management Portal, click Create.
• In the Add a new namespace dialog, enter a namespace name. The system immediately
checks to see if the name is available.

Microsoft Azure Shared Access Name and Key
Click Connection Information. In the Access connection information dialog, find the connection
string that contains the SAS key and key name. Make a note of these values, as you will use this
information later to perform operations with the namespace.

Mule Anypoint Microsoft Azure Connector
Configuration: This element must be placed outside of your
flows and at the root of your Mule application. You can
create as many configurations as you deem necessary
as long as each carries its own name.
Connection Pool : Azure connector offers automatic
connection management via the use of a connection
pool. The pool will act a storage mechanism for all the
connections that are in-use by the user of this
connector.
Reconnection Strategies : Reconnection Strategies specify
how a connector behaves when its connection fails.
You can control how Mule attempts to reconnect by
specifying a number of criteria

Mule flow
Steps to be followed for integrating 'Microsoft Azure' with MuleSoft Applications:
• Install the Microsoft Service Bus Connector in Anypoint Studio (3.5 and above)
http://repository.mulesoft.org/connectors/releases/3.5
• Create a new Anypoint Studio Project and Flow.
• Before using the Microsoft Service Bus Connector in the Mule Flows, create a global element
for ‘Microsoft Service Bus: Azure Service Bus’ configuration which can be reused in all other
flows across the Mule project - wherever the objects are created & deleted to & from
Microsoft Azure cloud server.

Mule Flow (cont.)
• Configure the ‘Microsoft Service Bus: Azure Service Bus’ connector by providing the following
information for the global element
– Service Namespace
– Shared Access Key Name
– Shared Access Key
• Use HTTP inbound endpoint to hit the service to pull the list of queues from the Microsoft
Azure storage server
• Configure the Microsoft Service Bus endpoint by providing the following to fetch the list of
queues from the Azure server -
– link to the ‘global Connector Configuration’
– Operation
