  • Nodes: 2

After a period of time, the current instance no longer met business requirements. The specifications were upgraded to 4 vCPUs | 16 GB at 9:00:00 on March 20, 2023. As you intend to use the DB instance for a long time, you changed the billing mode from pay-per-use to yearly/monthly at 10:30:00 on March 20, 2023. The subscription duration was one month. How much can you be billed for the DB instance in March and April?
