Working with AWS SQS FIFO Queues

You will have to complete the following steps to setup a FIFO Queue.

· First open the SQS Console window https://console.aws.amazon.com/sqs/

· Choose Create queue, specify the correct region.

· Standard queue is selected by default. Choose FIFO

· You cannot change the queue type after you create it

· Enter name for your queue. The name of a FIFO queue must end in the .fifo suffix.

· To create the queue with default parameters, scroll to the bottom and choose Create Queue. Amazon SQS creates the queue and displays the queue’s Details page
