Amazon EC2 Elastic IP Addresses

One of the problems with Amazon EC2 was the dynamic nature of the IP address that you received for each instance you started up.  For development it isn’t a big problem, but for a production system you can see the problems this can cause if you instance fails for some reason.  This morning Amazon announced the ability to have a static IP that is associated with your AWS account.  By default a user can have up to 5 static IP addresses.  The IP addresses are free of charge as long as the IP address is associated with a running instance.  If the IP isn’t then there is a charge of $.01/hr.  You can read more about this on the Amazon Web Services Developer site.
