Use Azure portal to create a Service Bus namespace and a queue

This quickstart shows you how to create a Service Bus namespace and a queue using the Azure portal. It also shows you how to get authorization credentials that a client application can use to send/receive messages to/from the queue.

What are Service Bus queues?

Service Bus queues support a brokered messaging communication model. When using queues, components of a distributed application do not communicate directly with each other; instead they exchange messages via a queue, which acts as an intermediary (broker). A message producer (sender) hands off a message to the queue and then continues its processing. Asynchronously, a message consumer (receiver) pulls the message from the queue and processes it. The producer does not have to wait for a reply from the consumer in order to continue to process and send further messages. Queues offer First In, First Out (FIFO) message delivery to one or more competing consumers. That is, messages are typically received and processed by the receivers in the order in which they were added to the queue, and each message is received and processed by only one message consumer.

QueueConcepts

Service Bus queues are a general-purpose technology that can be used for a wide variety of scenarios:

  • Communication between web and worker roles in a multi-tier Azure application.
  • Communication between on-premises apps and Azure-hosted apps in a hybrid solution.
  • Communication between components of a distributed application running on-premises in different organizations or departments of an organization.

Using queues enables you to scale your applications more easily, and enable more resiliency to your architecture.

Prerequisites

To complete this quickstart, make sure you have an Azure subscription. If you don't have an Azure subscription, you can create a free account before you begin.

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 addressing Service Bus resources within your application.

To create a namespace:

  1. Sign in to the Azure portal

  2. In the left navigation pane of the portal, select + Create a resource, select Integration, and then select Service Bus.

    Create a resource -> Integration -> Service Bus

  3. In the Create namespace dialog, do the following steps:

    1. Enter a name for the namespace. The system immediately checks to see if the name is available. For a list of rules for naming namespaces, see Create Namespace REST API.

    2. Select the pricing tier (Basic, Standard, or Premium) for the namespace. If you want to use topics and subscriptions, choose either Standard or Premium. Topics/subscriptions are not supported in the Basic pricing tier.

    3. If you selected the Premium pricing tier, follow these steps:

      1. 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, or 4 messaging units for each Service Bus Premium namespace. For more information, see Service Bus Premium Messaging.
      2. Specify whether you want to make the namespace zone redundant. The zone redundancy provides enhanced availability by spreading replicas across availability zones within one region at no additional cost. For more information, see Availability zones in Azure.
    4. For Subscription, choose an Azure subscription in which to create the namespace.

    5. For Resource group, choose an existing resource group in which the namespace will live, or create a new one.

    6. For Location, choose the region in which your namespace should be hosted.

    7. Select 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.

      Create namespace

  4. Confirm that the service bus namespace is deployed successfully. To see the notifications, select the bell icon (Alerts) on the toolbar. Select the name of the resource group in the notification as shown in the image. You see the resource group that contains the service bus namespace.

    Deployment alert

  5. On the Resource group page for your resource group, select your service bus namespace.

    Resource group page - select your service bus namespace

  6. 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) rule with an associated pair of primary and secondary keys 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 and secondary keys for your namespace, follow these steps:

  1. Click All resources, then click the newly created namespace name.

  2. In the namespace window, click Shared access policies.

  3. In the Shared access policies screen, click RootManageSharedAccessKey.

    Screenshot shows the Shared access policies window with a policy highlighted.

  4. In the Policy: RootManageSharedAccessKey window, click 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.

    Screenshot shows an S A S policy called RootManageSharedAccessKey, which includes keys and connection strings.

  5. Repeat the previous step, copying and pasting the value of Primary key to a temporary location for later use.

Create a queue in the Azure portal

  1. On the Service Bus Namespace page, select Queues in the left navigational menu.

  2. On the Queues page, select + Queue on the toolbar.

  3. Enter a name for the queue, and leave the other values with their defaults.

  4. Now, select Create.

    Queues -> + Queue -> Enter name -> Create

Next steps

In this article, you created a Service Bus namespace and a queue in the namespace. To learn how to send/receive messages to/from the queue, see one of the following quickstarts in the Send and receive messages section.
