The two long standing, well known and appreciated Azure Core Services (Azure Service Bus and Azure Event Hubs) just released a preview of an upcoming generally available Geo-disaster recovery feature. With the help of this feature, no client needs to manage Geo-disaster recovery scenarios anymore via code, but can instead rely on the services doing the metadata synchronization between two independent namespaces. At this time, data replication is not yet supported and will be added at a later (post General Availability) point in time.
