A quick note on how I'm currently handling Blue/Green or A/B deployments with Terraform and AWS EC2 Auto Scaling.
In my particular use case, I want to be able to inspect an AMI deployment manually before disabling the previous deployment.
Hopefully someone finds this useful, and if you have and feedback please leave a comment or email me.
I build my AMI's using Packer and Ansible.
