Create an AppFabric Service Bus
The following steps will guide you through the process of creating an AppFabric Service Bus on the AppFabric Labs.
Navigate to https://portal.appfabriclabs.com/ , and then sign in.
Select ‘AppFabric Services’ from the bottom left of the page.
Select ‘New Namespace’ from the ribbon at the top of the page.
In Available Services, ensure that only Service Bus is selected.
Enter a namespace, for example RubyQueue.
Select a region, for example United States (South/Central).
All other settings can remain as default.
Click ‘Create Namespace’.
Once the namespace status changes to Active (green), you can begin working with queues within this namespace.
