I configured for my AWS account the new AWS instance scheduler https://aws.amazon.com/answers/infrastructure-management/instance-scheduler/
The problem seems that, tagging ec2-instances through a scaling group the ec2-instances are correctly stopped, but since my scaling group has Min number set to 2 AWS scaling group restarts them anyway.
I would not like to set Min number to 0, just because is useful during application redeploy.
How to make the 2 services work fine?
