Amazon Simple Queue Service (SQS) Gains FIFO Queues

Amazon’s Simple Queue Service (SQS) recently gained FIFO (first-in, first-out) queues, which are designed to “guarantee that messages are processed exactly once, in the order that they are sent, and without duplicates”. AWS rolled out this new queue type in the US East (Ohio) and US West (Oregon) regions and “plans to make it available in many others in early 2017”.

Amazon SQS is described as a “fast, reliable, scalable, fully managed message queuing service [designed to] decouple the components of a cloud application [and] transmit any volume of data, without losing messages or requiring other services to be always available”.
