Wasted Usage- Resource usage that isn’t actively used by an organization.
RightSizing- Act of changing the size of provisioned resources to one that better matches needs.
On-Demand Rate- The normal or base rate paid for a cloud resource.
Rate Reduction- Using Reserved Instances (RIs), Committed Use Discounts (CUDs), or commercial agreeements between an organisation and a cloud service provider in order to receive a lower rate for the used resources.
Cost Avoidance- By reducing resource usage, either by removing a resource altogether or by rightsizing it, you can avoid paying for resources that would have incurred a charge.
Cost Savings- By reducing the rate you pay for resources, you generate savings.
Saving Potential- When looking at your cloud bill forecasts, you can predict the amount of saving using your existing commitments and commercial agreements.
Savings realized- By reducing the rate you page for resources, you generate savings.
Reservations/Commitments- By precommitting to a cloud service provider a set amount of resource usage using RIs or CUDs, you receive a reduction in the rate normally paid for those resources.
Reservations Unused/Unutilized- For every hour you have committed to a resource usage that you dont use, thatreservation goes unused, or unutilized. Another terms for this is reservation capacity.
Reservation Waste- Having a reservation with some amount of underutilization isnt an issue as longs as the discount you’re receiving is larger than the cost of the unused reservation.
Covered Usage- When a resource charge is discounted by a reservation, you call it covered.
Coverable Usage- Not all usage in the cloud is coverable with a reservation.
Unblended Rates- Some resources are charged in decreasing rates the more you use them
Blended Rates- Some cloud service providers offer a blended rate in their billing data. This blended rate standardizes the rate you page ofr the same type of resource by evenly distributing the charges to each resource.
Amortization- Costs that happended during a previous accounting period related to the current period based on the accumulated benefit during this period.
Amortized Costs- Some cloud resources and reservation come with an upfront fee.

COGS- Cost of goods sold measures how many dollars of outlay it takes to generate revenue in a specific period.
Net Present Value(NPV)- In a cloud business case, the net present value of all the cash flows of a no-upfront RI might be compared to the current cash value of the all-upfront RI for determining which is better for the business.
- It is most important for a finops team to determine the present value of future benefits when using reservations.
Unit Economics- It is the comparison between the total cloud cost that is required to produce a give unit of value to the organization.
