7. Message Broker
 Middleware, simple server
 Communication via AMQP
 Communication flow:
 Source application (sender) sends message to MB
 The MB stores it
 It deliveres the message to other application(s) (receiver(s))
 It takes the responsibility and complexity

8. Message Broker
 Point to point (Queues)
 Publish – Subscribe (PubSub)(Topics)

11. Message Brokers
 Azure Service Bus
 RabbitMQ
 AmazonMQ

12. Azure Service Bus
 Enterprise, fully managed messaging service
 Reliable and secure platform for async transfer
 High availability
 Decouple applications
 Supports queues, topics (1:N)
 Message in binary format

13. Azure Service Bus
 Namespace
 Queue
 Topic
 Subscription

14. Other advanced features
 Autoforwarding
 Dead-letter queue
 Filtering
 Autodelete on idle
 Geo-disaster recovery

15. .NET Libraries
 Microsoft Azure ServiceBus SDK
 Rebus
 Azure Service Bus
 RabbitMQ
 SqlServer
 Others

16. Sitecore Messaging
Framework

18. What is this?
 Supports message-based communication in Sitecore
 Wraps the Rebus Library
 Introduced in 9.0.1 (Only SQL Transport)
 Azure Service Bus support later
 Part of the XP, not part of the XM configuration
