Apple has confirmed that it uses Google’s public cloud to store data for its iCloud services in its latest version of the iOS Security Guide last month, as reported by 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.
The encrypted chunks of the file are stored, without any user-identifying information, using third-party storage services, such as S3 and Google Cloud Platform.
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.
