Triggering Auto-Scaling by Manually Hitting CPU% Max-Limit 💡

Ensuring your AWS instance can handle high traffic is crucial. One way to test auto-scaling is by manually increasing CPU utilization to hit the max limit, prompting AWS to scale.

Solution

To simulate high CPU usage for testing:

1. Install stress tool:

   Bash

    sudo yum install stress
   

2. Run stress to max out CPU:

   Bash

    stress --cpu <number_of_cores> --timeout <duration_in_seconds>
   

This will increase CPU utilization, triggering auto-scaling to match the desired instance count. 🚀

Example

Bash

stress --cpu 4 --timeout 600

This stresses 4 CPU cores for 600 seconds, testing your auto-scaling configuration. Happy testing! 📈.
