You can purchase and stack multiple resource plans that have the same duration. For example, if you purchase four new prepaid resource plans 2.0, each with a 1 year duration and 100 CU, you will have a monthly quota of 400 CU for one year. This quota offsets all billable items for Simple Log Service.
Note The quota for a new prepaid resource plan 2.0 resets to zero at the end of each month and is restored the following month.
