Operations and retrieval
Class A/B operations, retrieval fees, and early deletion.
Early Delete (EarlyDelete-ByteHrs)
On-demandA charge for deleting, overwriting, or moving an object before its storage class minimum duration has elapsed. You are billed as though the object had stayed for the full period. It is one of the least self-explanatory SKU names on a Google Cloud bill and one of the easiest to eliminate.
Billed: Charged for the unused remainder of a minimum storage duration, in byte-hours.
Class A and Class B Operations
On-demandCloud Storage bills for API calls as well as for bytes. Class A covers writes and listing; Class B covers reads. Listing is the one that catches people: it is a Class A operation, and code that lists a bucket in a loop can generate an operations bill larger than the storage bill.
Billed: Per 10,000 operations. Class A (writes, lists) costs roughly ten times Class B (reads).
