Microsoft Azure Queues Microsoft Azure

What is a Queue in Microsoft Azure?

The data structure used for storing data by First in-First out rule is defined as a Queue. The data item is inserted from the back of the queue and is retrieved from front. In the similar way Azure queues are used to store the messages in a queue. The message is sent by the sender and the client receives and processes the message.

The messages can be processed and deleted by the client. The message is stored for 7 days by the Windows Azure and after 7 days gets automatically deleted, if it is not deleted by the client. There can be one sender and one client or one sender and many clients or many sender and many clients.

There are two services offered by Windows Azure for message queues - Windows Azure queue and Service Bus queue.

Decoupling the components is one of the advantages of message queue services. It runs in an asynchronous environment where messages can be sent among the different components of an application. Thus, it provides an efficient solution for managing workflows and tasks. For example, a message to complete a task is sent from the frontend of the application and is received by a backend worker, who then completes the task and deletes the message.

Considerations

The messages in the Microsoft Azure queue do not have any replication. The maximum size of the message can be 40 kb and the number of replications can be processed is 20,000.
