Microsoft recently introduced a public preview of the Geo-Replication feature in Azure Service Bus’s premium tier. This feature ensures continuous replication of a namespace’s metadata and data from a primary to a secondary region, offering robust protection against outages and disasters.
Competitors like AWS SQS and Google Cloud Pub/Sub also offer high availability and disaster recovery features, but Azure Service Bus’s Geo-Replication provides a more integrated solution with synchronous or asynchronous namespace replication.
The Geo-Replication feature is available in specific Azure regions: Central US EUAP, Italy North, Spain Central, and Norway East.
