IOPS in AWS

IOPS (Input/Output operations per second)

It is important to understand the concept of the IOPS in the AWS environment.

It is measured in the 16KB chunks

You can calculate the provision IOPS by this formula

IOPS x 16kb / 1024 = MB tranfer per second

you can use the command iostat or sar in Linux to find the iops operation on Linux System.

The major application of iops come with the database operations.

As database can perform very high IOPS.

You can use the provision iops for getting the higher IOPS in EBS.

you can have 200 to 4000 provisioned IOPS, from the above formula we can calculate what the transfer per second is between the EBS and the instance.
