provider-specific documentation for how to configure networks

[lionello]

          I would like to see provider-specific documentation for how to configure the following scenarios:

| Subnet | Ingress | Egress | Example usage scenario | Notes |
| private | public ALB | public IP | web service | Default in Development deployment mode |
| private | public ALB | NATGW | web service with improved security | Default in Production deployment mode |
| private | private IP | public IP | worker node making external HTTP requests | ... |

Ideally with some mermaid diagrams to visualize the each topology.
