Ah, I crammed a bunch of threads in my terse answer. We use AWS because elastic beanstalk works better for our environment than heroku. Plus with S3 integration (and Route53), we found it doesn't make sense to maintain the OS and to keep everything on one cheap platform (cheap because it can be scaled up/down very quickly). Using the LB to send everything to :80 on a VPC means our devs don't need to dink with TLS on their remote laptops.
