Release Notes>Release: Amazon Simple Queue Service on 2006 07 11
Amazon Simple Queue Service (Amazon SQS™) is now generally available. Amazon SQS offers a reliable, highly scalable hosted queue for storing messages as they travel between computers. By using Amazon SQS, developers can simply move data between distributed application components performing different tasks, without losing messages or requiring each component to be always available. Amazon SQS works by exposing Amazon's web-scale messaging infrastructure as a web service. Any computer on the internet can add or read messages without any installed software or special firewall configurations. Components of applications using Amazon SQS can run independently, and do not need to be on the same network, developed with the same technologies, or running at the same time.
