+## Queue
+
+Azure Queue Storage is a service in Microsoft's Azure cloud platform designed for message queuing between application components, enabling asynchronous communication and decoupling. It allows you to store an unlimited number of messages, each up to 64 KB in size, and supports operations such as creating and deleting queues, adding, retrieving, updating, and deleting messages, as well as managing metadata and access policies. While it typically processes messages in a first-in-first-out (FIFO) manner, strict FIFO is not guaranteed. It is commonly used for managing workflows, processing tasks, and offloading tasks to improve application scalability and reliability.
