Communication Patterns

Queues and Topics
Both Queues and Topics are supported as message destinations
Transactions are sequences of send and receive operations grouped into atomic operations
Message Push Listeners
Asynchronously receive messages from one destination and either sends the messages to another destination or pushes them to a user-defined URL as an HTTP request
Standard Interfaces
Provides standard REST and JMS interfaces for interacting with the service programmatically

Reliability Mechanisms

Acknowledgement modes clients can set to acknowledge the messages they receive from the messaging service
Durable Subscription
A durable subscription saves messages sent to a topic for later consumption by a client consumer
Persistent Messages
Store messages in a durable medium to ensure they are not lost if the service is down
Retry and Failover Policies
Clients have the ability to define specific responses to network failures, failure to push the message to a destination, etc.
