The billing method of the read-only instance. Valid values: Monthly package and The pay-as-you-go billing method.
Note
- The subscription billing method is a pre-payment plan. This billing method is suitable
for long-term use in stable production environments. The unit price of the subscription
billing method is lower than that of the pay-as-you-go billing method.
- The pay-as-you-go billing method is a post-payment plan. This billing method is suitable

to USD 100.
