Availability Zones is a feature offered by Microsoft that allows protecting data and applications from failures that may occur in data centers. These are unique physical locations within an Azure region made up of several data centers each having an independent power supply and networking. All enabled regions possess at least three separate zones to ensure resiliency. This setup provides protection from data center failures while zone-redundant services replicate data across Availability Zones to mitigate single points-of-failure.
Enabling Availability Zones in Azure Service Bus Premium or Azure Event Hubs Standard
It is possible to enable Availability Zones on new namespaces only. Existing namespaces do not support this feature.
When creating a new namespace in an ARM template specify an Availability Zone and set the zoneRedundant property to true.

For Azure Event Hubs Standard namespace:
It is also possible to enable zone redundancy when creating a new template, however, it is important to note that it is not possible to disable it after it is enabled on a namespace. Below is the process of enabling zone-redundancy for a new template:
