 For this scenario, if we're using the provisioned v1 billing model, we must follow the provisioned storage requirements and over-provision our IOPS and throughput. Here are the reverse calculations on the IOPS and throughput to see how much we are over-provisioned.
-IOPS limit will be 102,400 + 3,000 = 105,400 IOPS
-Throughput limit will be 102,400\*0.1+100=10,340 MiB / sec
