Amazon SQS is a managed, highly scalable, and durable service that provides developers with a mechanism to store messages that can be later consumed by one or more applications. In this section, we will be exploring a few of the concepts and terminologies offered by SQS along with an understanding of which SQS, queue to use for what scenarios, so let's get started!

Here, the queues created offer a nearly-unlimited transaction per second (TPS) rate coupled with an at-least-once delivery model. What this model means is that a message can be delivered at least once, but occasionally there is a good probability that more than one copy of that same message can be delivered as well.
