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 This parameter is required for `io1` and `io2` volume types. The default for `gp3` volumes is `3,000 IOPS`. This parameter is not supported for `st1`, `sc1`, or `standard` volume types. This parameter maps 1:1 with the `Iops` parameter of the CreateVolume API in the Amazon EC2 API Reference.
