The AmazonSQS Component provides an easy interface to Amazon's Simple Queue Service (SQS).

Syntax

IPWorksMQ.Amazonsqs

Remarks

The AmazonSQS Component allows you to access Amazon's Simple Queue Service (SQS). SQS allows you to create globally accessible queues on Amazon's servers. These queues can be used by developers to transfer data between distributed application components, without losing messages or requiring each component to always be available. A brief synopsis follows but please refer to Amazon SQS documentation for details.

You will first need to sign up for the SQS service and obtain the AccessKey and SecretKey from Amazon. Then you can start creating queues in your account using CreateQueue. You can then start adding message's to the queue using CreateMessage and retrieve the same using ListMessages.

There are other methods such as ListQueues, DeleteQueue, DeleteMessage etc. that further enable you to manage your SQS queues.
