Create a Service Bus namespace using the Azure portal
A namespace is a scoping container for all messaging components. Multiple queues and topics can reside within a single namespace, and namespaces often serve as application containers. For more information about namespaces and other concepts of Azure Service Bus, see Service Bus - concepts.
This article provides instructions for creating a namespace in the Azure portal.
Create a namespace in the Azure portal
To begin using Service Bus messaging entities in Azure, you must first create a namespace with a name that is unique across Azure. A namespace provides a scoping container for Service Bus resources within your application.
To create a namespace:
Sign in to the Azure portal
In the left navigation pane of the portal, select + Create a resource, select Integration, and then select Service Bus.
In the Basics tag of the Create namespace page, follow these steps:
For Subscription, choose an Azure subscription in which to create the namespace.
For Resource group, choose an existing resource group in which the namespace will live, or create a new one.
Enter a name for the namespace. The namespace name should adhere to the following naming conventions:
- The name must be unique across Azure. The system immediately checks to see if the name is available.
- The name length is at least 6 and at most 50 characters.
- The name can contain only letters, numbers, hyphens “-“.
- The name must start with a letter and end with a letter or number.
- The name doesn't end with “-sb“ or “-mgmt“.
For Location, choose the region in which your namespace should be hosted.
For Pricing tier, select the pricing tier (Basic, Standard, or Premium) for the namespace. For this quickstart, select Standard.
If you want to use topics and subscriptions, choose either Standard or Premium. Topics/subscriptions aren't supported in the Basic pricing tier.
If you selected the Premium pricing tier, specify the number of messaging units. The premium tier provides resource isolation at the CPU and memory level so that each workload runs in isolation. This resource container is called a messaging unit. A premium namespace has at least one messaging unit. You can select 1, 2, 4, 8 or 16 messaging units for each Service Bus Premium namespace. For more information, see Service Bus Premium Messaging.
Select Review + create. The system now creates your namespace and enables it. You might have to wait several minutes as the system provisions resources for your account.
On the Create page, review settings, and select Create.
Select Go to resource on the deployment page.
You see the home page for your service bus namespace.
Get the connection string
Creating a new namespace automatically generates an initial Shared Access Signature (SAS) policy with primary and secondary keys, and primary and secondary connection strings that each grant full control over all aspects of the namespace. See Service Bus authentication and authorization for information about how to create rules with more constrained rights for regular senders and receivers.
To copy the primary connection string for your namespace, follow these steps:
On the Service Bus Namespace page, select Shared access policies on the left menu.
On the Shared access policies page, select RootManageSharedAccessKey.
In the Policy: RootManageSharedAccessKey window, select the copy button next to Primary Connection String, to copy the connection string to your clipboard for later use. Paste this value into Notepad or some other temporary location.
You can use this page to copy primary key, secondary key, primary connection string, and secondary connection string.
Congratulations! You have now created a Service Bus Messaging namespace.
