If you wish to run more than 20 On-Demand instances, complete the Amazon EC2 instance request form.

Amazon SQS can help you build a distributed application with decoupled components, working closely with the Amazon Elastic Compute Cloud (Amazon EC2) and other AWS infrastructure web services.

With Amazon SQS, you can move data between diverse, distributed application components without losing messages and without requiring each component to be always available.
