with ec2, are all internal instances able to connect to each other, or does the security group apply
- by Blankman
Just a little confused, normally a firewall applies to everything externally, and all internal servers (instances) can connect freely with each other.
With AWS, it comes with a firewall/security group.
Do these settings apply to each instance?
what about other customers, can there instances connect to my instances if I don't setup iptables on each instance?
