Is iCloud going to use Windows Azure!?

In recent weeks, Mary-Jo Foley, a journalist specializing in Windows for ZDNet, has received several indications that Apple would use Windows Azure, the platform-as-service Microsoft. She was dismissed out of hand these rumors, but the assumption seems to be confirmed now iCloud was presented.

Sending an image IMessage causes authentication to servers Windows Azure. The study of communications network connected to IOS devices icloud indeed shows contacts with Windows Azure servers and Amazon AWS in addition to Apple's servers, as shown, for example Apple Infinite. GigaOM has sought advice from three experts from the cloud: if two do not think that such communications be sufficient evidence, the third draws an explanation of interest.

Apple already has data centers, used especially for MobileMe and updates of software. They are however not sufficient to properly distribute the content around the world: Apple relies on a distribution network (CDN), provided in particular by Akamai and Limelight. The contents are duplicated on thousands of servers around the globe to accelerate downloads. So according to this third expert, Apple would use a similar strategy to icloud: the data center of Maiden would host the master files, but copies are placed on servers Windows Azure (and Amazon AWS) as a cache.

In light of new observations of network traffic on an iPhone with iOS 5, Infinite Apple has another theory: Apple's servers would not be used to store files, but to manage the links between different files, scattered servers, Windows Azure and Amazon AWS, as close to their users.

In any case in detail, the use of external services for icloud is not surprising. While the data center of Maiden is the ninth largest in the world, but Microsoft up three data centers in the top 10: the Redmond Company has one of the largest accommodation capacity in the world, with a system, Windows Azure that has nothing to prove. Apple is pragmatic on the matter: she knows the world of data center is not his strength, and does in fact not a single Mac in the Maiden. Windows Azure is also a product that Steve Jobs knows well: his other company, Pixar, had worked in the cloud version of its rendering engine, system demonstration in the Microsoft cloud.
