Publish-subscribe messaging is the cornerstone of reliable distributed applications. To better support a broader array of mission-critical cloud apps, we’ve introduced Azure Service Bus Premium messaging. This new tier provides all the messaging features of Service Bus queues and topics, with predictable, repeatable performance and improved availability.
Unlike the multitenant model used by Basic and Standard Service Bus tiers, the Premium tier uses a microservices model to provide resource isolation and more consistent performance. For more information, please visit the
