Analyzing RIs

RI Utilization

You can learn about the RI usage, including the amounts saved and amortized after using RIs, and monitor the comprehensive utilization rate of your RIs.

RI utilization = Number of used RI hours/Number of purchased RI hours x 100%

1. Log in to Cost Center.
2. Choose Reserved Instances.
3. Click RI Utilization.
4. Set search criteria to view the RI utilization.

   

   ① You can select Monthly, Daily, or Hourly for a period of time from the last 18 months.

   • Monthly: You can view the utilization data from the last 3, 6, or 12 months. Also you can manually search for data within a specific period (18 months at most).
   • Daily: You can view the month-to-date utilization, and also the utilization from the last 7 days, 14 days, 30 days, or 3 months.
   • Hourly: You can view the utilization from 00:00 to 24:00 for a given day.
   ② This area displays the utilization data for the queried period.

   Table 1 RI utilization fields

   Field	Description	Example
   Pay-per-Use Cost Equivalent	Pay-per-use costs equivalent to the RI hours you have used, calculated based on the list price.	Example: You purchase an RI with a duration of 100 hours. The price of a pay-per-use resource with the same specifications is $4 USD per hour. This pay-per-use resource has matched the RI for 6 hours. Scenario 1: No upfront fee is charged for the RI, and the hourly rate is $1.5 USD. In this case: Pay-per-use cost equivalent = 4 x 6 = $24 USD RI cost = 1.5 x 6 = $9 USD Total net savings = 24 – 9 = $15 USD Total potential savings = 4 x 100 – 1.5 x 100 = $250 USD Scenario 2: A partial upfront fee of $40 USD is charged for each RI, and the hourly rate is $1 USD. In this case: Pay-per-use cost equivalent = 4 x 6 = $24 USD RI cost = 40/100 x 6 + 1 x 6 = $8.4 USD Total net savings = 24 – 8.4 = $15.6 USD Total potential savings = 4 x 100 – (1 x 100 + 40) = $260 USD Scenario 3: An upfront fee of $100 USD is charged for each RI. In this case: Pay-per-use cost equivalent = 4 x 6 = $24 USD RI cost = 100/100 x 6 = $6 USD Total net savings = 24 – 6 = $18 USD Total potential savings = 4 x 100 – 100 = $300 USD
   RI Cost	Cost of used RIs amortized by hour. RI cost = Upfront costs for purchased RIs amortized by hour + Cost charged amortized by hour
   Total Net Savings	Total amount saved by using the RI compared to pay-per-use pricing Total net savings = Pay-per-use cost equivalent – RI cost
   Total Potential Savings	Potential savings that may be realized if RIs are all used up. Total potential savings = Pay-per-use cost equivalent for purchased RI hours – RI cost

   ③ This chart shows your utilization over time.

   Example: If you purchase a 100-hour RI and the matched pay-per-use resource has been used for 6 hours, the RI utilization is 6% (6/100 x 100%).

   ④ The Filters area is designed for you to include or exclude certain types of data. You can select up to 50 items for each filter.

RI Coverage

RI coverage lets you know what percentage of pay-per-use resources are covered by your purchased RIs so that you can evaluate whether you have purchased enough RIs.

Coverage = RI covered hours/Total resource running hours x 100%

1. Log in to Cost Center.
2. Choose Reserved Instances.
3. Click RI Coverage.
4. Set search criteria to view the RI coverage.

   

   ① You can select Monthly, Daily, or Hourly for a period of time from the last 18 months.

   • Monthly: You can view the coverage data from the last 3, 6, or 12 months. Also you can manually search for data within a specific period (18 months at most).
   • Daily: You can view the month-to-date coverage, and also the coverage from the last 7 days, 14 days, 30 days, or 3 months.
   • Hourly: You can view the coverage from 00:00 to 24:00 for a given day.
   ② This area displays the coverage data for the queried period.

   Table 6 RI coverage fields

   Field	Description	Example
   Average Coverage	The average coverage rate within the queried period. Coverage = RI covered hours/Total resource running hours x 100% RI covered hours refer to the used RI hours. Total resource running hours refer to the total used hours of the pay-per-use resource.	Example: You purchase an RI and run two pay-per-use resources for 10 hours each. The hourly rate of the pay-per-use resources is $4 USD. One pay-per-use resource has matched the RI for 4 hours. In this case: Coverage rate = 4/20 x 100% = 20% Total pay-per-use cost = (20 – 4) x 4 = $64 USD
   Pay-per-Use Total	Total pay-per-use costs for pay-per-use instances not covered by the used hours in the query period.

   ③ This chart shows your coverage over time.

   Example: If a pay-per-use resource runs for 10 hours and matches the RI for 4 hours, the coverage rate is 4/10 x 100% = 40%.
