negative.code: Before you deploy your application to Cloud Foundry, make sure that:
  
  * Your application is *cloud-ready*.
  Cloud Foundry behaviors related to file storage, HTTP
  sessions, and port usage may require modifications to your application.
  
  * All required application resources are uploaded. For example, you may need to include a database driver.
  
  * Extraneous files and artifacts are excluded from upload. You should explicitly exclude extraneous files that
  reside within your application directory structure, particularly if your application is large.
  
  * An instance of every service that your application needs has been created.
