S3 Storage Class Automation: Stop Paying Hot Prices for Cold Data

A typical production S3 bucket at 18 months old has accumulated objects across every feature that ever ran. The initial uploads from your onboarding pipeline. The exports from the analytics job that ran twice and was deprecated. The thumbnails from the old image processing service. The log archives from before you switched to CloudWatch. Run S3 Inventory on a bucket that has been active for a year and the pattern is always the same: 70-80% of objects have a last-accessed date older than 90 days.
