Should I deploy ember and rails web application on AWS Beanstalk or CodeDeploy?

I want to deploy a web application which uses ember for frontend, ruby on rails for backend and postgreSQL as my DB. The frontend and backend were separated into two directory: myApp/client and myApp/server. The reason why I separate them is that they have some namespaces(model view controler) in common.However, they communicate with each other by given urls. So should I deploy a specific ruby app on Beanstalk or install the entire environment in a EC2 instance and then deploy it through CodeDeploy?
