Azure Service Bus Queues belong to the Azure messaging framework and include queuing, publishing, subscribing, etc. They are part of the Service Bus and can pass messages through to other Queues and Topics. The Azure Service Bus Queues feature a built-in dead-letter queue and allow you to choose a timeline for messages so they can last as long as you want them to! They connect applications or parts of applications that cover different communication protocols, data treaties, trust domains, or security protocols.
Azure Storage Queues belong to the Azure storage framework and are easy to use. They allow easy debugging by using the local Azure Storage Emulator. The set of Azure Storage Queue tools enables you to take a quick look at the top 32 messages and visualize the contents of those belonging to XML/JSON right from Visual Studio. Another feature of storage queues that ensures smooth development and QA operations is that the contents of these queues can be emptied when needed. Authenticated HTTP or HTTPS calls allow you to access the queue messages regardless of your geographical location. Queue messages have a maximum capacity of 64 KB and can hold millions of messages depending upon the storage account's overall capacity limit.
