Cloud Storage Classes

Google Cloud Storage classes: Standard, Nearline, Coldline and Archive, priced by access frequency.

Definition

All classes offer millisecond access and the same APIs. Nearline has a 30-day minimum storage duration (data accessed about once a month), Coldline 90 days (about once a quarter) and Archive 365 days (less than once a year). Colder classes have lower storage cost but higher retrieval fees. Autoclass can transition objects automatically.

Example

Disaster recovery backups accessed once a quarter are stored in Coldline.

Exam tip

Unlike AWS Glacier Deep Archive, Google's Archive class still provides millisecond retrieval; the trade-off is cost and minimum duration.
