Reusable IaC Module

Problem

Twenty teams need the same secure Azure Storage configuration. Each copies 300 lines of Bicep and modifies them slightly. Soon you have twenty subtly different implementations.

Solution — Reusable Module

Encode the approved pattern once.

Storage Module
      ↓
Team A
Team B
Team C

Teams supply necessary parameters instead of rebuilding the architecture.

Core idea: IaC modules turn repeated infrastructure patterns into reusable building blocks.
