Using SQS (Simple Queue Service)
By enabling the SQS add-on, you can enable your application to work with a queue backed by Amazon's Simple Queue Service.
Overview
The SQS Add-on creates a FIFO queue and gives the app access to it via its task role. No static access keys are necessary.
Destroying the application will destroy the queue and all messages left in it
