Queue

As explained in Microsoft Azure in Action

A queue is a first-in-first-out data structure in which items are added at the back and removed from the front.

A queue is a first-in-first-out line: add messages at the back, retrieve them from the front. Azure Queue Storage holds data objects up to 64 KB and can scale to millions of messages. section 5.5

Holding orders for later processing

Banning Books places incoming book orders in a queue before processing them, preventing a rush of orders from overwhelming the order processor. A message such as “Banned book order 123456” waits its turn. section 5.5

A practical Azure Queue Storage workflow includes:

  • Create a queue inside an existing storage account with New-AzStorageQueue. section 5.5
  • Insert a CloudQueueMessage, then retrieve queued messages from the front. section 5.5
  • Treat access permissions as part of the setup; the queue also exposes a URI for HTTP/HTTPS access. section 5.5

How Microsoft Azure in Action covers it

How deep it goes
Explains FIFO behavior, message size, capacity, creation, insertion, retrieval, and access, but stops short of processing internals.
Examples
Uses Banning Books orders, a banned book order message, PowerShell commands, and an Azure Queue Storage flow diagram.
What it assumes
Assumes an existing storage account, storage context, and permissions configured for access.
What you can do after
Operate/configure Azure Queue Storage by creating a queue, adding a message, and retrieving queued data with PowerShell.
How it connects
Connects Azure Queue Storage with storage accounts, blob storage, PowerShell, and HTTP/HTTPS access.
