AWS Service: Reserved Instance (RI) Reporting
Question: What are the different fields and metrics available in RI Reporting and how can they be leveraged for cost optimization?
Answer:
RI Reporting provides various fields and metrics to help customers understand their AWS Reserved Instance (RI) usage and optimize their costs. Some of the important fields and metrics available in RI Reporting are:
Instance Type: This field shows the type of EC2 instance that the RI is applicable for.
Availability Zone: This field shows the availability zone in which the RI is applicable.
Offering Type: This field shows the type of offering, such as Standard or Convertible.
Offering Class: This field shows the offering class, such as Standard or Scheduled.
Purchase Option: This field shows the purchase option, such as All Upfront, Partial Upfront, or No Upfront.
Instance Count: This metric shows the number of instances that the RI is applicable for.
Utilization: This metric shows the percentage of RI utilization for a given time period.
Coverage: This metric shows the percentage of covered usage by the RI for a given time period.
Unused Hours: This metric shows the number of unused hours for the RI during a given time period.
Amortized Upfront Fee: This metric shows the amortized upfront fee for the RI during a given time period.
These fields and metrics can be used to analyze RI usage, identify opportunities for cost optimization, and plan future RI purchases. For example, by analyzing the utilization and coverage metrics, customers can identify instances that are underutilized or not covered by RIs, and purchase additional RIs to optimize their costs. By analyzing the unused hours metric, customers can identify RIs that are not being utilized and potentially modify or exchange them to optimize costs.
