Billing Examples

Billing Scenario

A user purchased a pay-per-use GeminiDB Cassandra instance at 15:30:00 on March 18, 2023. The instance configuration is as follows:

• Specifications: 2 vCPUs | 8 GB
• Nodes: 3
• Public network bandwidth: 6 Mbit/s

After a period of time, the user found that the current GeminiDB Cassandra instance specifications no longer met service requirements and updated the specifications to 4 vCPUs | 16 GB at 09:00:00 on March 20, 2023. Since the user wanted to use the instance long term, the user then changed the instance to yearly/monthly billing with a one-month duration at 10:30:00 on the same day. So how much will the user be billed for this GeminiDB Cassandra instance in March and April?
