In the planning phase you analyze your requirements and define the structure of the distributed system. An analysis of your requirements shows you how many hosts you need and the tasks that the hosts will carry out.

To simplify the installation and configuration of the system, you should create the following during the planning phase:

  • A graphical depiction of the distributed system

  • A table containing the host names and roles of the hosts involved
