Apple is reportedly now Google Cloud’s largest customer in terms of storage.

Apple had been known to be a Google Cloud customer since as far back as 2016. In 2018 the company confirmed via an iOS Security Guide it was a Google customer, saying it stored parts of encrypted iCloud information using third-party storage services such as S3 and Google Cloud Platform.

This week, The Information reported that the Cupertino company was on track to spend around $300 million on Google cloud storage this year, an increase of around 50 percent on 2020.

The company reportedly added 470 petabytes stored on GCP last year – the same as all the storage used by Google's next- largest customer, TikTok maker ByteDance – bringing the total amount of data it had on Google's cloud to more than 8 exabytes.

Apple’s status as the platform’s largest customer and reportedly ‘dwarfing’ other high-profile GCP customers have led to staff have giving Apple the internal code name ‘Bigfoot.'

Spotify was Google's third-largest customer with about 460 petabytes of data, Twitter fourth with 315 petabytes, and Snapchat fifth with about 275 petabytes.

Despite being such a large cloud customer, Apple also has a sizeable data center footprint. The company has a number of data centers in the US including Nevada, Oregon, and North Carolina, as well as a campus in Viborg, Denmark, in addition to facilities in China operated by in-country partner Guizhou Cloud.

The company is planning another facility in Iowa, but its opening has been pushed back from 2020 to 2027.

Apple recently requested an extension on planning permission for a data center in Athenry, Ireland, potentially reviving a project thought abandoned several years ago.

The company also canceled plans for a second data center in Denmark in 2019.
