  13. rhel tomcat java app Another Distro One package manager -

    automated patches Reuse Isolated app. One hierarchy security Conf. Mngt.
  14. Demo

  15. development ... software development and release processes

  20. beaurocracy … the administrative system governing any large institution

  21. Generated Versioned Deliverable Shared Searchable { } … Starts and
