Billing Examples

Suppose you purchased a one-month RDS for MySQL primary/standby DB instance (instance class: general-purpose 2 vCPUs | 4 GB; storage: cloud SSD 40 GB; backup space: 50 GB (40 GB for free); bandwidth: 6 Mbit/s; one-second monitoring) on March 08, 2023, 15:50:04, and renewed the subscription for one more month before the initial subscription expired. That would include two usage periods:

  • Billed usage period 1: March 08, 2023, 15:50:04 to April 08, 2023, 23:59:59
  • Billed usage period 2: April 08, 2023, 23:59:59 to May 08, 2023, 23:59:59
    • From April 08, 2023, 23:59:59 to May 01, 2023, 23:59:59, 20 GB of free backup space was used.
    • From May 01, 2023, 23:59:59 to May 08, 2023, 23:59:59, another 10 GB of backup space was used, which was billed for 168 hours.
    • Monitoring by Seconds was enabled at 23:59:59 on May 04, 2023. Fees were generated from 23:59:59 on May 04, 2023 to 23:59:59 on May 08, 2023 (96 hours).
