Percent Storage on Frequent Access Tier
Definition
Measure of the percent of object storage stored on a Frequent Access Tier. The ideal percentage is not standard across all cloud environments, but measuring the percentage of total storage in a frequent access tier (ex: S3 Standard) can help organizations spot-check. Storage costs consist of a tradeoff between persistent storage costs vs. access and data transfer fees. Many companies can host 50%+ (sometimes, much higher!) in infrequent or “cold” storage (ie.g. AWS Glacier).
