PowerShell, Graphs, Topology and Real Use Cases
summary
Practical PowerShell tooling ingests metadata (Windows event logs, DNS, firewall XML, Azure subscription exports) and builds dependency graphs using a wrapped graph library. The PowerShell module loads thousands of objects from over 200 Azure subscriptions to produce a ~1,700-node, ~1,400-edge graph in about 15 minutes, runs path/search algorithms to find items like VNets connected to ExpressRoute, and drives automated actions such as repointing networks; code and exporters are provided and the system reconstructs real dependencies from messy environments.
