Azure Durable Message Buffers

Last year at PDC 2010, the Azure AppFabric team made a number of important announcements. One of the improvements they released was a significantly enhanced version of the Azure AppFabric Service Bus Message Buffers feature.[windows_azure[3].jpg]

What’s the difference between the current Message Buffers and the new Durable Message Buffers?

The current version of Message Buffers provide a small in-memory store inside the Azure Service Bus where up to 50 messages no larger than 64KB can be stored for up to ten minutes. Each message can be retrieved by a single receiver. This makes the range of scenario’s where this is useful somewhat limited. The new version of Message Buffers enhance this feature so it could have a much wider appeal. Message Buffers are now durable and look much more like a queuing system. This makes it possible to start using Durable Message Buffers as an alternative to the Azure Queues.
