Exercise - Create your Azure Service Bus Premium namespace
In this unit, you'll learn how to create your Azure Service Bus Premium namespace.
Introduction to Azure Service Bus
Azure Service Bus is a fully managed enterprise message broker with message queues and publish-subscribe topics. Service Bus is used to decouple applications and services from each other, and it provides the following benefits:
- Load balances work across competing workers
- Safely routes and transfers data and controls across service and application boundaries
- Coordinates transactional work that requires a high degree of reliability
Some common messaging scenarios are:
- Messaging: Transfer business data, such as sales or purchase orders, journals, or inventory movements.
- Decouple applications: Improve reliability and scalability of applications and services. Producer and consumer don't have to be online or readily available at the same time. The load is leveled such that traffic spikes don't overtax a service.
- Load balancing: Allow for multiple competing consumers to read from a queue at the same time, each safely obtaining exclusive ownership to specific messages.
- Topics and subscriptions: Enable 1:n relationships between publishers and subscribers, which allows subscribers to select particular messages from a published message stream.
- Transactions: Do several operations, all in the scope of an atomic transaction.
- Message sessions: Implement high-scale coordination of workflows and multiplexed transfers that require strict message ordering or message deferral.
If you're familiar with other message brokers like Apache ActiveMQ, Rabbit MQ, TIBCO EMS, and IBM MQ, then Service Bus concepts are similar to what you know.
Create a Service Bus namespace
Start by creating the namespace. In Azure Service Bus, a namespace is a container for queues and topics. Each namespace has a unique, fully qualified domain name, with primary and secondary shared access signature (SAS) encryption keys. A sending or receiving component must provide an SAS key to gain access to objects in a namespace.
Sign in to the Azure portal with the same credentials that you used to activate the sandbox. Open the link in a new tab or a new window, and keep it side-by-side with the Learn module content.
Under Azure services, select Create a resource.
In the Create a resource pane, enter Service Bus in global search. In the search results, select Service Bus published by Microsoft for Azure, and then select Create.
In the Create namespace pane, on the Basics tab, enter or select the following values for each setting:
Setting Value Description Project Details Subscription Concierge subscription The subscription in which this new app is created. Resource group [Sandbox resource group name] The name of the resource group in which to create your Service Bus namespace. In this exercise, you'll create the namespace in the resource group that was assigned when you activated the sandbox. Instance Details Namespace name [Globally unique name] Enter a name that is unique in Azure.
If you want to use the format salesteamapp<Company><year>, your namespace name would look like the example salesteamappContoso2022.
Location Select from the dropdown Choose from the free sandbox regions listed after this table. Pricing tier Premium Support for Java Message Service (JMS) 2.0 API is only available with the Premium tier.
The free sandbox allows you to create resources in a subset of the Azure global regions. Select a region from the following list when you create resources:
- West US 2
- South Central US
- Central US
- East US
- West Europe
- Southeast Asia
- Japan East
- Brazil South
- Australia Southeast
- Central India
Select Review + create.
When validation succeeds, select Create to create your Service Bus namespace.
When deployment is finished, select Go to resource.
Create a Service Bus queue
Next, add a queue for messages about individual sales to your namespace:
- On the Service Bus Namespace page, select Queues under Entities on the left menu.
- Select + Queue on the command bar.
- In the Create queue pane, for Name, enter test-queue-jms, and then select Create.
When the message queue has been created, test-queue-jms is listed under Queues at the bottom of the Service Bus namespace pane.
Get connection string to the namespace
You'll use the namespace's connection string later in this training to connect to the Service Bus namespace from a JMS app.
- On the Service Bus Namespace page, select Shared access policies under Settings on the left menu. \
- Select RootManageSharedAccessKey on the Shared access policies page.
- On the SAS Policy page, select the Copy button next to Primary connection string field. \
- Paste it and save it so that you can use it later in the training.
