Domain 3.1: Storage Performance — AWS SAA-C03 Practice Question 40

How to approach this question

Identify the EFS performance mode designed for big data and high IOPS.

Full Answer

Change the EFS performance mode to Max I/O.<br/>Ensure the application is highly parallelized.

If the PercentIOLimit metric is hitting 100%, the file system is maxing out the IOPS available in General Purpose mode. You should migrate to a file system using Max I/O mode, which scales to higher levels of aggregate throughput and IOPS. Max I/O requires applications to be highly parallelized to overcome slightly higher per-operation latencies.

Common mistakes

Thinking you can just change the mode on an existing file system (you actually have to create a new one and migrate data, though the concept is to use Max I/O).
