Yeah, that was my suspicion. From a cost optimization perspective, I don't think SQS will ever hit the level of price per instruction that RabbitMQ does. SQS also doesn't get anywhere near spitting distance on latency either. For my needs, though, it's always done a great job on reliable throughput. If you have folks with deep expertise with RabbitMQ, I can see why you'd go with it. It means that you can essentially neutralize its operational risks and maximize its strength, which is performance (as well as great integration codebase maturity).
