Amazon S3字节小时计费方式咨询：具体计算逻辑与数据采集频率

Great question! Let me break down how byte-hours work for S3 billing based on AWS's official details:

• Hourly snapshot tracking: AWS calculates byte-hours using hourly snapshots of your stored objects. Every hour, it records the size of each object currently in your buckets. For each object, it multiplies its size by the number of hours it’s stored—partial hours are rounded up to the next full hour.
  • Example: If you upload a 1GB object at 2:30 PM and delete it at 4:15 PM, it counts as 1GB × 1 hour for the 2–3 PM window, 1GB × 1 hour for 3–4 PM, and another 1GB × 1 hour for 4–5 PM—even though it only existed for part of the first and last hours.
• Not triggered by operations: PUT/POST/DELETE actions modify your storage, but they don’t kick off immediate byte-hour calculations. The next hourly snapshot will just capture the updated state (new object added, existing one removed) and adjust the tally accordingly.

In short, S3 tracks your storage usage on an hourly basis, not per operation or at 5-minute intervals.
