![]() Select Notification Hub Namespaces in the Internet of Things section. Use the Azure portal to edit an existing namespace. Enable cross-region disaster recoveryĬross-region disaster recovery options can be modified at any time. See the Back up registration data section for options for preserving the registration data for your namespace and how to restore it. When a disaster recovery scenario is triggered, registration data is the only segment of the Notification Hubs infrastructure that is lost. You can use the Azure paired region or choose from a list of supported flexible regions. Notification Hubs provides metadata disaster recovery coverage through cross-region replication of metadata (the Notification Hubs name, the connection string, and other critical information). See the Notification Hubs pricing page for tier details to determine which features are supported on each tier. You can use these options in tandem or separately, where tier support is provided. You can only configure availability zones for new namespaces at this time. This feature is available for an extra cost for all tiers. 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. If the primary copy fails, one of the secondary copies is promoted to primary with no perceived downtime. To ensure resiliency, a minimum of three separate availability zones are present in all availability zone-enabled regions. Tolerance to failures is achieved because of redundancy and logical isolation of Azure services. Failures can range from software and hardware failures to events such as earthquakes, floods, and fires. Zone redundant resiliency uses Azure availability zones. These zones are physically separate locations within each Azure region that are tolerant to local failures. West Us 2 - North Europe - Australia East - Brazil South - South East Asia - South Africa North See Azure cross-region replication pairings. In regions with availability zones and no region pair, you can use flexible recovery to choose a failover region that provides resiliency in the event of a full region failure. All tiers provide a flexible recovery region option, enabling you to choose from a list of supported regions. All Notification Hubs tiers support Azure paired regions (where available). Each Azure region is paired with another region within the same geography. Cross-region is supported in paired and flexible region recovery options. Notification Hubs offers two availability configurations:Ĭross region disaster recovery provides metadata disaster recovery coverage. Ability to edit your cross region disaster recovery options.If you are interested in using these features, contact your customer success manager at Microsoft, or create an Azure ticket, which will be triaged by the support team: The following features are available in preview. ![]()
