The Geo-Replication feature for Azure Service Bus in the
premium tier is now generally available. The Service Bus Geo-Replication
feature is one of the options to insulate
Azure Service Bus applications against outages and disasters, providing
replication of both metadata (entities, configuration, properties) and data
(message data and message property / state changes).
The Geo-Replication feature ensures that the metadata and
data of a namespace are continuously replicated from a primary region to one or
more secondary regions. Moreover, it allows promoting any secondary region to
primary, at any time.
Promoting a secondary repoints the endpoint for the
namespace to the selected secondary region and switches the roles between the
primary and secondary region. The promotion is nearly instantaneous once
initiated and doesn’t require any changes on the client side.
More information on this feature can be found in the documentation.
