Pattern to deploy AWS Beanstalk in laravel

I have been following this guide:

http://ift.tt/2lfV1ya

However I am stuck at this point.

Not in terms of something not working, but in how it should be done properly. Which app I should deploy?

Is is the development app that is tested and deployed? Do I create another instance in AWS that will be only used to deploy ready apps? What is the pattern to follow?

At the moment I have local development server which runs on my PC, and also 1 Development instance EC2 on AWS. Do I need more than that on top of Elastic beanstalk?

Please advice me! Thanks!
