Azure Service Bus equivalent

The new version of Service Bus Explorer supports browsing messages in a Queue without dequeueing them.

It makes use of the new Peek feature in Service Bus SDK 2.0

QueueClient queueClient = QueueClient.Create("myQ");
BrokeredMessage message = queueClient.Peek();

If you need 10K or 100K or 1M or more requests per seconds take a look at what's being done on the highway. More traffic, more lanes.

You can get effectively arbitrary flow rates out of Service Bus by partitioning your traffic across multiple entities. Service Bus gives a number of assurances about reliability, e.g. that we don't lose messages once we took them from you or that we assign gapless sequence numbers, and that has throughput impact on the individual entities like a single Topic. That's exactly like a highway lane just being able to deal with X cars/hour. Make more lanes.
