Fabric Capacity Planning - Paying by the Hour?
Thank you for the response. I have reviewed the links you shared, which I had read previously. I still don't think I have a direct answer to my direct qustion. My question is: How is the smoothing calculated if you pause/suspend a capacity every day, so you only pay for 8 hours a day (as an example.). Is the smoothing still calculated over 24 hours of actual time? 24 hours of when the capacity is running - so over 3 days in my example? the 8 hours the capacity is running within the 24 hours of actual time?
To spell out my example even more. Let's say that I have a process where I have my capacity running only from 8 AM to 4 PM every day - so 8 hours. Let's say I have a background process that will smooth over 24 hours, that takes 240 CU usage. Which of the following will be how that usage is actually smoothed:
| Day 1 | Day 2 | Day 3 | |
| spread over 24 clock hours | 10 CU usage per hour | ||
| spread over 24 hours of capacity running | 10 CU usage per hour for 8 hours | 10 CU usage per hour for 8 hours | 10 CU usage per hour for 8 hours |
| spread over the 8 hours capacity is running in the 24 hours | 30 CU usage per hour for 8 hours |
Hi, jon_clemens
Thank you very much for your reply. The description I found in the documentation is: The amount of capacity provided by the given SKU per 30-second period is shown along with the breakdown of interactive and background operations.
In this section, an example of a price calculation:
