     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](/rest/api/servicebus/create-namespace).
     2. Select the pricing tier (Basic, Standard, or Premium) for the namespace. If you want to use [topics and subscriptions](../articles/service-bus-messaging/service-bus-queues-topics-subscriptions.md#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 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](../articles/service-bus-messaging/service-bus-premium-messaging.md).

For more information, see [Service Bus Premium Messaging](../articles/service-bus-messaging/service-bus-premium-messaging.md).
         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](../articles/availability-zones/az-overview.md).
     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.
