Hi @devpavan ,

The error suggest that you're using Free Tier - and specified instance you're  trying to create is not eligable for Free Tier. 
So, to me it looks like you have Free Free/Trial AWS Account and probably hit this limitation/

So, you can do what they suggest. Run below command and check what types of VMs are elgible in Free Tier. Then try to create compute that is aligned with that.

run 'describe-instance-types' with the filter 'free-tier-eligible=true'
