Nadie mantiene al día el diagrama de red de AWS. He hecho una herramienta para eso

VPC Atlas is an MIT licensed tool designed to automate AWS network diagrams for draw.io and Lucidchart, solving the problem of outdated manual drawings. It uses read-only calls to map VPCs, Transit Gateways, peerings, VPN, and Direct Connect. To ensure trust in a single-person project, the author implemented a public CI/CD pipeline and supply chain checks. This allows users to verify binaries, as the tool requires AWS account credentials to execute its functions.
