I came cross a nice Diagram as Code tool, it allows me to draw Cloud system architecture in Python code.
To use it, you need to install Graphviz and diagrams python module.
brew install graphviz
pip install diagramsHere is a sample code of using the tool to create the diagram of AWS transit gateway network architecture.

| tgw – DirectConnect("direct connect") – OfficeBuilding("on-premise") | |
| tgw – SiteToSiteVpn("vpn connection") – VPCCustomerGateway("customer gateway") |
Run the script python tgw-diagram.py, then you will see the nice diagram 😉
