Introducing Availability Zones GA for Azure Notification Hubs

Heather Tian

We are excited to announce another new general available feature that improves the high availability of your push notifications: Availability Zones. This feature is available for an extra cost of $350 a month for all tiers. Starting October 9th, all customers including those who were previously in preview will begin to be billed for the feature add-on. You can only configure availability zones for new namespaces at this time.

These zones are physically separate locations within each Azure region that are tolerant to local failures. Failures can range from software and hardware failures to events such as earthquakes, floods, and fires. Tolerance to failures is achieved because of redundancy and logical isolation of Azure services. To ensure resiliency, a minimum of three separate availability zones are present in all availability zone-enabled regions. If the primary copy fails, one of the secondary copies is promoted to primary with no perceived downtime. During a zone-wide outage, no action is required during zone recovery; the offering self-heals and rebalances itself to automatically take advantage of the healthy zone. You can easily enable Availability Zones for your Azure Notification Hubs through the Azure portal. To learn more about how to enable and use Availability Zones for Azure Notification Hubs, please refer to our documentation: Azure Notification Hubs Availability Zones
