Jordan Novet, CNBC:
Apple periodically publishes new versions of a PDF called the iOS Security Guide. For years the document contained language indicating that iCloud services were relying on remote data storage systems from Amazon Web Services, as well as Microsoft’s Azure.
But in the latest version, the Microsoft Azure reference is gone, and in its place is Google Cloud Platform. Before the January update, Apple most recently updated the iOS Security Guide in March.
When news of this deal first broke nearly two years ago, I was surprised that Apple was still so dependent on third parties for iCloud storage. I understand that these things take time, but iCloud is seven years old this year, and Apple has been providing various internet services for decades.
Apple maintains that they control the encryption keys and that Google cannot possibly intercept iCloud users’ data, which is true — with the possible exception of email, since it is stored unencrypted — but I don’t think that iCloud users expect their data to be stored in ways not entirely controlled by Apple, especially given the company’s emphasis on privacy.
