Hello,
From the CloudWatch Metrics [1],
EBSIOBalance% :: Provides information about the percentage of I/O credits remaining in the burst bucket. This metric is available for basic monitoring only.
EBSByteBalance% :: Provides information about the percentage of throughput credits remaining in the burst bucket. This metric is available for basic monitoring only.
Burst Balance (Percent) :: The BurstBalance metric measures the remaining percentage of the Burst Balance for your volume.
That being said, EBSIOBalance% monitors the instance I/O burst bucket, and EBSByteBalance% monitors the instance byte burst bucket. These metrics give information about the percentage of I/O or bytes credits remaining in the respective burst buckets. EBSIOBalance%, EBSByteBalance% are instance level metrics that are available only for nitro instances and BurstBalance is a volume level metric.
Whereas in case of gp2 volumes it don’t have provisioned IOPS, they have a Burst Balance that allows them to temporarily do more operations. The BurstBalance metric measures the remaining percentage of the Burst Balance for your volume. Consistently using the Burst Balance is a sign that you need to upgrade your volume, and you should monitor for this condition.
Kindly refer the following blog for detailed information on how to use these metrics.

Now several questions:
