Multiple queue worker

Hi, I'm facing a situation where the application has 2 queue workers, the first one is for the hard work, where it could be images and OCR processing. The second one is for notifications, emails, and payment processing. My web application is now going to run in the AWS EC2 Autoscaling Group with LoadBalancer. How could I set up the queue workers? I was prior using google cloud compute engine, in a single server where it was managed with horizon, supervisor and such stuff. But I am now confused about how to set it up with multiple queue workers in an autoscaling group PS: I was thinking about using forge but fell more comfortable working directly in AWS Console.
