It's as simple as reading a message that comes to the queue and then, removing the message from the queue by setting a status as 'Complete'. Post the lock duration time period, the message will be available for the rest of the receivers. When a message is peek-locked, it will not be available for any other receiversДЇor the valid lock duration. This is also commonly referred to as Non-Destructive Read. Peek-lock(ing) a message means retrieving the message from the queue but locking the message for further processing. To the topic are not directly received by the receivers instead, they are received from the subscriptions. Similarly, another subscriber can only receive POs whose purchase request is from a particular party.

Say, one subscriber can have filter rules to receive the POs with the value greater than 10,000. Orders (POs) are being sent through the topic.

On the other hand, Topics offer a one-to-many messaging mechanism where a single published message is capable of being retrieved by multiple subscribers depending on predefined filter rules applied for every subscriber. The communication is only one way and the sender needs not have to wait to receive a response from the receiver end Queues allow a unidirectional way of communication between devices based on a First In First Out (FIFO) message delivery mechanism. Azure Service Bus (Brokered) Messaging includes Queues and Topics as the main communication services while Azure Relay offers support to different transport protocols and web services such as REST, SOAP, and WCF.
