Two huge new features were announced today for EC2. The first being Elastic IPs which is basically the static IP solution everyone has been waiting for, but better! Elastic IP is a 1:1 NAT solution. What is so cool about this is you can dynamically remap your static IP to different running instances creating a poor mans HA solution. The second feature is Availability Zones. This allows you to launch instances in isolated zones that amazon describes as “distinct locations engineered to be insulated from failures in other zones.” The next step to this is allowing for region specific selection as well, currently you are limited to selecting a zone within your defined region based on your account. This provides for a huge increase in availability and will certainly make organizations take another hard look at what amazon has to offer to extend or augment their existing facilities.
