## Overview

Axion is a Terraform configuration for provisioning a modular Azure network and compute topology. The documented workflow is an operator applying the dev environment, whose entrypoint calls child modules to provision a resource group, virtual network, subnets, public IPs, and Linux VMs. The README describes frontend, backend, and database subnet roles and four VM roles (UI, telemetry query, ingestion, and database). No source excerpts were provided, so relationships below rely on the README; implementation details beyond its documentation are not inferred.

Main entry points: [`environments/dev/main.tf`](https://github.com/devopsinsiders/axion-monolithic-infra/blob/main/environments/dev/main.tf) (Dev environment), [`modules/azurerm_virtual_network/main.tf`](https://github.com/devopsinsiders/axion-monolithic-infra/blob/main/modules/azurerm_virtual_network/main.tf) (Virtual network), [`modules/azurerm_public_ip/main.tf`](https://github.com/devopsinsiders/axion-monolithic-infra/blob/main/modules/azurerm_public_ip/main.tf) (Public IPs), [`modules/azurerm_linux_virtual_machine/main.tf`](https://github.com/devopsinsiders/axion-monolithic-infra/blob/main/modules/azurerm_linux_virtual_machine/main.tf) (Linux VM fleet)
