AWS launched the Amazon Simple Queue Service (SQS) in 2004 and the Amazon Simple Notification Service (SNS) in 2010.
Today AWS are making SQS and SNS an even better value:
SQS API prices will decrease by 50%, to $0.50 per million API requests.SNS API prices will decrease by 17%, to $0.50 per million API requests.The SQS and SNS free tiers will each expand to 1 million free API requests per month, up 10x from 100K requests per month.
The new prices take effect on March 1, 2013 and are applicable in all AWS Regions with the exception of the AWS GovCloud (US).
