How to find “IOPs per instance type” info in AWS?

Problem:

An instance’s EBS performance is limited by the performance of its attached volumes or the instance, whichever is lower.

When attaching volumes, we need to consider the instance type’s limitations on maximum IOPs.

Let’s determine the maximum IOPs that the target instance type can provide.

Solution:

There are multiple sources of information available, however, some of them are dry and lack detail.

I will provide two possible ways to check that info in detail:

AWS webpage: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-optimized.html

AWS CLI:

 aws ec2 describe-instance-types \
 --instance-types r5.2xlarge \
 --query InstanceTypes[].EbsInfo

In the above example, we used the r5.2xlarge instance type. Please specify your desired instance type to determine its corresponding EBS information.
