You can purchase a resource consumption plan for a specified duration for a specified region. After the instances take effect, the resource consumption plan can be deducted by second for the resources consumed by your reserved instances and pay-as-you-go instances within the lifecycle of the instances. If the resource consumption plan can cover the resources that are consumed, you do not need to pay for the resources. Otherwise, you need to pay for the part of the resources that is not covered by the resource consumption plan.
Example: User A has function A and function B in Shanghai. At 19:35:56 on August 30, 2019, function A matches two reserved instances of 1 GB and has consumed three pay-as-you-go instances of 1 GB. Function B matches four reserved instances of 2 GB and has consumed five pay-as-you-go instances of 2 GB. In the second of 19:35:56 on August 30, 2019, user A consumed resources of
(2 x 1 GB + 3 x 1 GB) + (4 x 2 GB + 5 x 2 GB) x 1 s = 23 GB*S in total. If user A has subscribed resources of 20 CUs that are active at 19:35:56 on August 30, 2019, user A only needs to pay for resources of 3 GB*S in this second. If user A has subscribed resources of more than 23 CUs that are active, user A does not need to pay for the resources.
