This update had a certain amount of commotion due to the appearance of Google Cloud in it. In the change Apple indicated that they use Google Cloud for iCloud storage .
This change has triggered more than one alarm, because of the possibility that since the data is on Google’s servers and not Apple’s own, someone could access users’ personal data through a back door . But the truth is that the use of third party servers is not something new, for years Apple has used S3 from Amazon or Microsoft Azure among others.
These servers store iCloud data such as a user’s contacts, calendars, photos, documents, preferences… everything that is synchronized between your devices. According to CNBC, Apple has confirmed the use of Google Cloud in its security guide.
This is what the official Apple safety guide says:
This change therefore need not be relevant to the user, Apple has always used third party servers (other than its own) to meet user demand in the use of iCloud. The access that Google will have to this information is the same as Amazon or Microsoft previously: null. Given Google’s reputation in recent years for using the data to offer personalised advertising, it can be concluded that in this case too, but it is completely different to hire a Google server to use its services in a professional manner.
