Does AWS throttle CPU Usage?
I am new to cloud and have 5 distributed instances on AWS running the same images. I have attached an image of the CPU usage CloudWatch monitor here:
2 of my instances are running at 100% but 3 of them drop to 0%. There are still tasks being processed and I would like the other 3 instances to run without idling until all the tasks are completed. What is going on here and how can I fix it?

Are you using T2 Instances ?
T2 instances are designed to provide moderate baseline performance and the capability to burst to significantly higher performance as required by your workload
You can get more information from below link for Initial CPU credit available for t2 series of instances.
