Changing Pay-per-Use to Yearly/Monthly

Optimization Options

Cost Center evaluates optimization options based on the usage of your resource usage within the last 7, 30, or 60 days. Cost Center:

1. Collects the costs and usage of your pay-per-use resources within a period you specify.
2. Estimates monthly usage and expenditures.
3. Searches for any yearly/monthly subscriptions that can be applied to these pay-per-use resources, and calculates their monthly amortized costs.
4. Identifies situations where the monthly amortized costs are less than the monthly expenditures, and offers you an opportunity to optimize your costs.

Important Notes

Currently, only ECS, EVS, RDS, ELB, and SFS Turbo costs can be optimized by changing the billing mode from pay-per-use to yearly/monthly.

If you are using a master account and have enabled unified accounting management, Cost Center will also analyze the costs and usage of your member accounts during the association period and offer you the optimization evaluation records for your member accounts.

Cost Center provides evaluations based on the assumption that your historical costs and usage will be similar in the future. It does not forecast your usage while estimating your monthly usage and does not consider any forecasted data when making the evaluation.

Optimization options are evaluated and updated daily after 17:00 (GMT+08:00).

Changing Pay-per-Use to Yearly/Monthly

   This function is enabled by default. You can disable it at will

   Parameter	Description
   Estimated monthly expenditure before optimization	The estimated monthly original cost of pay-per-use resources within the specified time range before an optimization. For example, if Data From is set to Last 60 days, the calculation would be as follows: Estimated monthly expenditures before optimization = (Amount due of pay-per-use resources over the last 60 days)/60/24 x 730 NOTE: 730 is used as the default number of hours per month.
   Monthly amortized cost after optimization	The monthly amortized cost that is calculated based on the specified subscription term after the optimization. For a monthly subscription, the monthly amortized cost is equivalent to the price of the monthly subscription. For a 1-year subscription, the monthly amortized cost is equivalent to the price of the 1-year subscription divided by 12.
   Linked Account	Account that uses the pay-per-use resource.
   Service Type	Service type of the pay-per-use resource.
   Specifications	Specifications of the pay-per-use resources.
   Resource Name/ID	Name or ID of the pay-per-use resource.
   Enterprise Project	Enterprise Project selected when you purchase the pay-per-use service.
   Usage	Usage of pay-per-use resources in a specified historical period.
   Estimated Monthly Expenditure	Estimated monthly pay-per-use expenditures for resources in the specified historical period.
   Subscription Term	Term of a yearly/monthly subscription as the optimization option recommended for pay-per-use resources.
   Monthly Amortized Cost	Estimated monthly amortized cost calculated after the billing mode of a pay-per-use resource is changed to yearly/monthly.
   Estimated Monthly Savings	Estimated amount that can be saved after the billing mode of a pay-per-use resource is changed to yearly/monthly. Estimated monthly savings = Estimated monthly expenditure – Monthly amortized cost
   Break-Even Time	For a monthly subscription, the calculation would be as follows: Break-even time (days) = Price of the recommended monthly subscription/(Estimated monthly expenditure/730 x 24) For a yearly subscription, the calculation would be as follows: Break-even time (months) = Price of the recommended yearly subscription/Estimated monthly expenditure
   Operation	If you click Pay-per-Use to Yearly/Monthly, you will be switched to the specific service management console, where you can change the billing mode. NOTE: Before changing the billing mode from pay-per-use to yearly/monthly, you are advised to confirm the application scenario with your business team. If you are using a master account and have enabled unified accounting management, you can download the optimization evaluation report and give it to your member accounts for reference, but cannot directly change the pay-per-use billing mode to yearly/monthly for your member accounts.
