Where Composer is used?

Engine Yard Cloud recognizes you have a composer.lock file in your repository when you publish your PHP application. If you do, it launches composer, which takes in the data and gets the needed packages from your composer.lock file. When all packages are installed successfully by the composer and the autoload script for your application is created, Engine Yard Cloud removes a symlink and replaces this symbol with a link to your existing deploy. Basically Composer commend runs in a Command Prompt as shown in the picture.
