Over the past month, I received a couple of tips claiming that Apple was a Windows Azure customer.
At first, I just dismissed the tips as nothing but a crazy rumor. Then I got more serious and started asking around, to no avail.
But once Apple launched the beta of its iCloud iMessage service, the Infinite Apple site, along with a few other blogs, analyzed the traffic patterns and found that Apple appeared to be using both Azure and Amazon Web Services for hosting.
