Plan

• Creation of interacting scheme for 5 main elements:

• Choose platform for web server:

  • CherryPy
  • NGINX + gunicorn + Django

  NGINX + gunicorn + Django was choosen as the web server platform due to:

  • recommended production environment

• Choose way of interaction of TeleManager application and TeleDatabase:

  • Django ORM
  • Python Class based

  Django ORM has been choosen due to convenience.

• Figure out distribution model:

  • Docker Container:
    • Single container with TeleManager, TeleBot, TeleEngine, TeleDatabase
    • 2 Dedicated container:
      • TeleManager, TeleBot, TeleEngine
      • TeleDatabase
  • Single application, which requires the user to install the database and application on the machine barely

  2 Dedicated container was chosen as distribution model due to:

  • Learning of Docker objectives
  • Fast deployment
  • Microsegmentation

• Create template for NGINX config

• Code TeleManager

• Code TeleBot

• Code TeleEngine

• Code distribution (images, docker-compose)
