What should be the best approach to managing iptables and host in scalable architecture? If four app servers were load balanced with eight servers, the four app servers need to talk to the eight servers as required and securing the server environment because no private network or separate IP will be used.
What is the best approach in iptables management?
The key element of this task is to understand how the server environment will behave in various situations. That understanding comes from spending time observing the system and examining data. That said, there are many configuration management tools (e.g., puppet) that exist for the purpose of managing servers, whether it is a few dozen servers or several thousand. These tools automate many tasks. This could also be accomplished through simple scripts provided the person scripting has an intimate understanding of their system. You can also use scripts that others provide. I suggest using a search engine to locate both software and scripts.
