Instance-time
The compute time is the total amount of time that your instances are running in a given month. For example, if you have 1 instance running the entire month, then the compute time would 730 hours (365 days * 24 hours per day divided by 12 months). If you have 10 instances also running all the time, then the compute time would be 730 * 10 = 7300 hours.
