  When you push an application, Cloud Foundry automatically detects which buildpack is required and installs it on the Diego cell or Droplet Execution Agent (DEA) where the application needs to run.
  
  <p class="note"><strong>Note</strong>: Cloud Foundry deployments often have limited access to dependencies. This limitation occurs when the deployment is behind a firewall, or when administrators want to use local mirrors and proxies.
