I have successfully install load balancing and auto scaling on AWS based on it's official tutorial : http://docs.aws.amazon.com/gettingstarted/latest/wah-linux/awsgsg-wah-linux.pdf
but, I have a question once it's up and running :
as we all know, if we want to have load balancing, of course we will have multiple EC2 instance. my question is, how to create, update or delete a file in an EC2 instance then automatically sync across all available EC2 instance under a load balancer?
thank you.
