We recently rediscovered Amazon SQS and are using it for two upcoming systems. Back in 2012 and 2013 we wanted to use it, since it eliminated the need to host RabbitMQ ourselves. However, SQS didn't support FIFO queues at the time. They eventually added it in 2016, but we had been using RabbitMQ for years, and we hadn't noticed this new development in a tool we didn't use. But we recently had a little trouble setting up RabbitMQ with Terraform, and we discovered SQS is easily supported with Terraform, and has all the features we once wanted.
