I have a web site that runs on an Amazon EC2 Linux-based instance, and is mapped to a regular domain name (x.com). This site talks to a database on a second EC2 instance.
I need to shut down this instance and increase the computing power behind it... if I do that, how long will it take, and then when I spin the machine up again, will my site just come back online? Will the IP address, DNS info etc. all be preserved so the domain name will keep working, and it will still be able to talk to the DB?
FYI this is what I currently see for the web server in the AWS EC2 info panel (exact IP addresses changed slightly but you get the idea):
Public DNS: ec2-54-1-1-1.us-west-1.compute.amazonaws.com Private DNS: ip-10-1-1-1.us-west-1.compute.internal Private IPs: 10.1.1.1
