[Question] setup with networked EC2 instances

[vsoch]

Hi! :wave: I'm new to terraform, and I'm looking to create a set of EC2 instances that can see one another. I've done this on Google Cloud, and for that strategy I use a common module to setup networking, and then I have some logic in the startup script to use the Google metadata API to get the ips for other instances. I'm looking for a similar setup for AWS - and this looks really close to what I'm interested in (but I have some questions!)

• For the multiple EC2 instances example - can the multiple instances automatically see one another by hostname? How do hostnames map to ip addresses?
• Is it possible to create multiple EC2 instances from AMI images (and different AMI images) on this same network setup?
• What are best practices to share ip addresses between the instances?

Thanks for your help!
