* Simplest to spin up in AWS with free tier offering 1M free messages
* The service must be long **polled** for messages
* Offers high throughput Standard "at least-once-delievery" which requeues a message if it was consumed from the queue and a visibility timeout passes
* Can also do up to 3k message/sec when order important with SQS FIFO "exactly once delivery"
* Base rate of 20k+/sec with more expensive options to request
* Messages must be less than 256KiB in size, but can turn it into S3 object
