How does IBM COS pricing work?

Storage costs for IBM COS are determined by total volume of data stored, the amount of public outbound bandwidth consumed, and the total number of operational requests processed by the system.

What is the difference between ‘Class A’ and ‘Class B’ requests?

‘Class A’ requests are operations that involve modification or listing. This includes creating buckets, uploading or copying objects, creating or changing configurations, listing buckets, and listing the contents of buckets.

‘Class B’ requests are those related to retrieving objects or their associated metadata/configurations from the system.

There is no charge for deleting buckets or objects from the system.

Class Requests Examples
Class A PUT, COPY, and POST requests, as well as GET requests used to list buckets and objects Creating buckets, uploading or copying objects, listing buckets, listing contents of buckets, setting ACLs, and setting CORS configurations
Class B GET (excluding listing), HEAD, and OPTIONS requests Retrieving objects and metadata

What is the difference between the Standard, Vault, and Flex billing tiers?

Vault billing is a way to control costs for infrequently accessed data, such as compliance or backup data. These objects incur lower storage costs but higher costs for operational requests. Unlike the Standard billing tier, additional costs are incurred on a per-GB basis for objects retrieved from the system. Flex billing is intended for use when data access patterns are difficult to predict, and pricing is optimized based on frequency of access.
