Application architecture of Ali-Bey deployed as a Docker multi-container application. A user connects with a web browser through the Internet to an Nginx web server that gives access to the application. The application is implemented with the Django web framework that interacts with the map server Geoserver and with the PostgreSQL/PostGIS database with the help of the Python HTTP server Gunicorn. The PostgreSQL alphanumeric and spatial database files and the layer metadata are all persistently stored in the host filesystem, configured as a Docker volume.
