Amazon Simple Queue Service (Amazon SQS) is a distributed message queuing service introduced by Amazon.com as a beta in late 2004, and generally available in mid 2006.^[1][2] It supports programmatic sending of messages via web service applications as a way to communicate over the Internet. SQS is intended to provide a highly scalable hosted message queue that resolves issues arising from the common producer–consumer problem or connectivity between producer and consumer.

Amazon SQS can be described as commoditization of the messaging service. Well-known examples of messaging service technologies include IBM WebSphere MQ and Microsoft Message Queuing. Unlike these technologies, users do not need to maintain their own server. Amazon does it for them and sells the SQS service at a per-use rate.
