Geo-disaster recovery for Azure Event Hubs is now enabled in all Azure regions. You can now enable this configuration on your existing namespaces and new namespaces in the region of your choice.
This feature gives you the flexibility of picking a primary region and a primary namespace in it to pair with a secondary namespace in a different region. Once paired, this feature maintains the sync of the entities between these regions. So in the event of a regional disaster and Event Hubs being unavailable in the primary region, you initiate a fail-over. Once the fail-over is initiated, the Event Hubs in the secondary region takes charge so you can continue with your application.
The Geo-DR feature also introduces the alias configuration which represents the pairing of the primary and secondary namespaces. Once Geo-paired, you can obtain the connection string to the alias which can be used by the clients to talk to Event Hubs. With this, when a fail-over is initiated, the connection to the primary is cut and the clients now talk to the secondary namespace without having to change the clients.
This release foes not contain data disaster recover-ability. This feature currently covers meta-data only recovery.
