Tagging all your Amazon resources is a must-have if you want to have an efficient billing follow-up. It’s very simple
in most cases, but not always. Like with EBS volumes within an auto-scaling group.
Even if it’s not natively possible, there is always a solution with AWS.
AWS provides one powerful feature called auto-scaling. If you configure it on your infrastructure, you will be
able to automatically adjust capacity to maintain optimal performances at the lowest possible cost.
But the downside is that it will be more difficult to open an SSH connection on your EC2 instances because the IP
addresses associated will change regularly.
