High Ratio of S3 API Costs to Storage Costs

This insight identifies when spend on API requests to an S3 bucket represent greater than 80% of costs for that bucket. This high ratio of requests to storage cost may indicate that there is frequently accessed data that could be moved to a different storage class.

When API requests costs are high, this may be because the data being accessed is in an Infrequent Access tier. While Infrequent Access tiers have lower storage costs, there is a cost for every gigabyte of data retrieved and it is billed as an API request.

Consider moving frequently accessed data to Standard storage tier, which does not charge for data retrieval, to save up to 50% on S3 spend.

Some Items to Note:

A small fee is applied for objects transitioned between storage classes, which is usually very low. Learn more about S3 pricing and the additional costs associated with S3 here.
