Billing examples
Subscription
You purchase a subscription instance for one month in the Singapore region. The subscription instance has 4 CCUs and 200 GB of cache. If the instance stores data of 500 GB during this month, the total monthly fee of the instance is USD 192. The fees of billable items are calculated based on the following formulas:
Computing resource fee = USD 36.980 per CCU-month × 4 CCUs × 1 month = USD 147.92.
Cache size fee = USD 0.152 per GB-month × 200 GB × 1 month = USD 30.40.
Storage resource fee = USD 0.000038 per GB-hour × 500 GB × 30 days × 24 hours = USD 13.68.
Pay-as-you-go
You purchase a pay-as-you-go instance in the Singapore region and use the instance for one hour. The instance has 4 CCUs and 200 GB of cache. If the instance stores data of 500 GB during this hour, the total fee of the instance is USD 0.347. The fees of billable items are calculated based on the following formulas:
Computing resource fee = USD 0.069170 per CCU-hour × 4 CCUs × 1 hour = USD 0.277.
Cache size fee = USD 0.000253 per GB-hour × 200 GB × 1 hour = USD 0.051.
Storage resource fee = USD 0.000038 per GB-hour × 500 GB × 1 hour = USD 0.019.
