We are excited to announce Elastic IP addresses and Availability Zones, two features that were among the top requests of Amazon EC2 developers (view press release). These new capabilities allow developers to achieve greater reliability and redundancy for their applications in the cloud, especially hosting websites. Unlike traditional static IP addresses, Elastic IP addresses can be dynamically remapped on the fly to point to any Amazon EC2 instance. Also available is the ability to launch instances in multiple Availability Zones, each with its own reliable, physically independent infrastructure, which allows developers to build fault resilient web applications through simple API calls. Read more about these new Amazon EC2 features.
