About Autoscaling

After I set up auto-scaling group, if I made some change in one EC2 instance within this group, will this change be updated to other launched instances? How about future automaticall provisioned instances because of the traffic demand increasing?

Thanks in advance to anyone trying to help!

    No, the instances are still independent of eachother. You would need to create a new AMI, add it to the launch configuration, then redeploy. There are various methods of redeploying, such as a rolling upgrade, or you can destroy all at once and replenish with new instances.
