Hi @dsingh07

Had tested with m5.xlarge but there is failure in cloudformation saying the AMI is not ENA enabled

Enhanced networking with the Elastic Network Adapter (ENA) is required for the 'm5.xlarge' instance type. Ensure that you are using an AMI that is enabled for ENA.

This needs to be fixed a AMI level as per blog https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking-ena.html

Hi @uptownaravi

Is it possible to find the latest equivalent of our Centos 7 AMIs that we currently have which may support enhanced networking? If that works, we can include that in the PR.
