Azure Queue storage is a service for storing large numbers of messages that can be accessed from anywhere in the world via authenticated calls using HTTP or HTTPS. A single queue message can be up to 64 KB in size, and a queue can contain millions of messages, up to the total capacity limit of a storage account. A storage account can contain up to 200 TB of blob, queue, and table data. See Azure Storage Scalability and Performance Targets for details about storage account capacity.
Common uses of Queue storage include:
- Creating a backlog of work to process asynchronously
- Passing messages from an Azure Web role to an Azure Worker role
The Queue service contains the following components:
- URL format: Queues are addressable using the following URL format:
http://<storage account>.queue.core.windows.net/<queue>
