Is iCloud utilizing Microsoft Azure and Amazon’s cloud services?

We’ve received an interesting tip today from someone who set up Charles as a WiFi proxy on their iPad to get a glimpse at the HTTP traffic which occurs when an image is sent through iMessage. Interestingly enough, it seems that iCloud somehow utilizes Amazon’s AWS cloud services as well as Microsoft Azure.

icloud.com provides some sort of authentication to a windows.net address, and then sends a confirmation back to iCloud. Image downloads come from an s3.amazonaws.com address. This process is visible in the screenshots above (click to enlarge).

We presume that iCloud isn’t entirely based on these other cloud services; it would be much more reasonable to deduce from these images that the other services are being used as some sort of CDN to take the load off of Apple. It’s also possible that, once iOS 5 and iCloud come out of beta and Apple’s own datacenters are completely ready, Apple will stop using these other cloud services altogether. We’ll just have to wait and see.

    I guess they are using Azure for Windows users wanting to sync to the cloud (after all there’s iTunes and Safari for Windows).

    Nice try. The user was on a Mac. Apple is building new data centers to serve hundreds of millions of devices. Yeah, nothing could possibly go wrong.

  • PT

    Apple is great a consumer market… right now they don’t have expertise to build and manage a complex data center infrastructure….so, nothing more than the expected to buy services from whom really knows how to do that (i.e. Microsoft and Amazon)

    “they don’t have expertise to build and manage a complex data center infrastructure”

    Hope you know the number of downloads App Store and iTunes Store have served.

    When I download songs from iTunes in Belgium it comes from a mirror server at a big belgian ISP (***.belgacom.net) – Apple has indeed no experience in managing data centers at the scale of public cloud services.

    There are iPhone, iPad and Android apps with their back-end running on Windows Azure. It’s end-device and broswser agnostic and can even run Java and PHP. It would make sense to segment customers’ data based on their end device.

    Typo; it would NOT make sense to segment customers’ data based on end device

    I’ve taken a olook at those headers and here’s some basic analysis and guess work as to what Apple are doing.http://www.syringe.net.nz/2011/06/10/AppleICloudRunningOnWindowsAzureAndAmazonS3.aspxAny chance of getting the full headers chris.auld(at)intergen.co.nz so I can take a proper look at exactly which features they are using.

    Yeah, before it was iCloud was introduced it was heard in news that they are going to use Windows Azure for cloud platform.

  • Krusty Old IT Guy

    iTunes store is just a drop in the bucket for what many large IT shops do. Apple is is great for consumers, but they are immature in terms of large, scaled out data centers. I wouldn’t be surprised to find out there whole web infrastructure was Linux!  ;^)

    Hm, I don’t recall those reports. Have any links?

    “ It’s also possible that, once iOS 5 and iCloud come out of beta and Apple’s own datacenters are completely ready, Apple will stop using these other cloud services altogether.”

    Or maybe not. Could it be that Apple’s clouds services might exist in an ecosystem of cloud services. Even to the point of being part of the cloud in a broad sense. That is the whole point of cloud. If Apple want to concentrate on presenting certain types of services they could very well prefer to use other infrastructural services from other parties.

    And maybe too of course as they may want to own the entire stack but Apple in general are really good at staying focused on stuff that is important to them and not getting sidetracked. What is an infrastructural content delivery network versus end user content provision services? There is potentially a lot of differences between shoveling blobs around and value add such as (for example) search, billing, promotions and sales integration that Apple can focus on and make profitable.
