Thanks. If I'm reading this https://ibb.co/bNGmrCB correctly, it seems like we have plenty burst balance. Does this seem to indicate that provisioned IOPS is unlikely to help us here?
Yeah you're looking good though I would recommend adding a CloudWatch alert to make sure it doesn't sneak up on you. IIRC in general provisioned IOPS can help with other performance attributes like throughput so I would look at the differences documented by AWS and then take a look at all of the relevant metrics to be certain.
