iops

The number of I/O operations per second (IOPS). For `gp3`, `io1`, and `io2` volumes, this represents the number of IOPS that are provisioned for the volume. For `gp2` volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting. The following are the supported values for each volume type: + `gp3`: 3,000 - 16,000 IOPS + `io1`: 100 - 64,000 IOPS + `io2`: 100 - 256,000 IOPS For `io2` volumes, you can achieve up to 256,000 IOPS on instances built on the Nitro System. On other instances, you can achieve performance up to 32,000 IOPS. This parameter is required for `io1` and `io2` volumes. The default for `gp3` volumes is 3,000 IOPS. This parameter is not supported for `gp2`, `st1`, `sc1`, or `standard` volumes.
