Frequently Asked Questions
What's the difference between logical and physical diagrams?
Physical diagrams show actual hardware and cabling. Logical diagrams show data flow and network segmentation regardless of physical location. Both are useful.
How do I show cloud infrastructure?
Use cloud provider icons or abstract cloud shapes. Show connections between on-premise and cloud resources. Group cloud services within cloud boundaries.
Should I include IP addresses?
Include IPs for documentation diagrams but consider removing them from diagrams shared externally for security. The tool supports IP labels on devices.
