Examples
Scenario 1 - Monthly Usage
Your workload runs less than 100 ops/sec for 20 days, and then bursts up to 250 ops/second for 5 days. Then, for another 3 days, the workload bursts to 500 ops/second.
Usage | Cost |
|---|---|
Your workload runs less than 100 ops/sec for 20 days. | $0.011/hour * 24 hours * 20 days = $5.28 |
The workload bursts up to 250 ops/second for 5 days. | $0.0288/hour * 24 hours * 5 days = $3.46 |
The workload bursts to 500 ops/second for another 3 days. | $0.0411/hour * 24 hours * 3 days = $2.96 |
Total Usage Charge | $5.28 + $3.46 + $2.96 = $11.70 |
Scenario 2 - One Day Use
Your workload runs less than 100 ops/sec for 5 hours. It bursts up to 410 ops/second for 10 hours, followed by 9 hours at 150 ops/second. After these 24 hours, you delete the cluster.
Usage | Cost |
|---|---|
Your workload runs less than 100 ops/sec for 5 hours. | $0.011 hourly base cost * 5 hours = $0.055 |
The workload bursts up to 410 ops/second for 10 hours. | $0.0411/hour * 10 hours = $0.41 |
The workload drops to 150 ops/second for another 9 hours. | $0.0205/hour * 9 hours = $0.18 |
You delete the cluster. | (no charge) |
Total Usage Charge | $0.055 + $0.41 + $0.18 = $0.65 |
