// Welcome to the Amazon Simple Queue Service API Reference.
//
// Amazon Simple Queue Service (Amazon SQS) is a reliable, highly-scalable hosted
// queue for storing messages as they travel between applications or microservices.
// Amazon SQS moves data between distributed application components and helps
// you decouple these components.
//
// Standard queues (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/standard-queues.html)
// are available in all regions. FIFO queues (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html)
// are available in US West (Oregon) and US East (Ohio).
//
// You can use AWS SDKs (http://aws.amazon.com/tools/#sdk) to access Amazon
// SQS using your favorite programming language. The SDKs perform tasks such
// as the following automatically:
//
//    * Cryptographically sign your service requests
//
//    * Retry requests
//
//    * Handle error responses
//
