Automating Azure Platform Deployment using a Root Module - Sopra Steria (Ordina)

During my internship at Sopra Steria, I worked on automating the deployment of Azure cloud resources using Infrastructure as Code (IaC) principles. The objective was to simplify and accelerate the process of setting up Azure infrastructure by leveraging Terraform, Azure DevOps, and a modular root module designed to handle the management and connectivity layers of the Azure Enterprise Scale Model.

The Cloud Center of Excellence (CCoE) has deployed Azure platforms for several customers using multiple Terraform modules. My project addressed key challenges, such as the complexity of managing numerous variable files, the need for dynamic naming conventions, and ensuring scalability across different environments. To solve these issues, I designed a YAML-based configuration system, merging it with Terraform local variables to define, manage, and deploy resources like virtual networks, subnets, firewalls, and DNS zones.

The root module I developed centralized resource configurations, allowing users to define their requirements in a single YAML file. By integrating this module into an Azure DevOps pipeline, the deployment process became more streamlined and scalable. Although my initial solution utilized a single pipeline for deploying across multiple subscriptions, I laid out plans for future enhancements, such as creating separate pipelines per subscription and integrating advanced security measures like SAST and DAST scans.

This project not only reduced deployment complexity but also ensured consistency and efficiency in resource management. Through this internship, I gained extensive experience in Terraform, Azure DevOps, cloud automation, and best practices in IaC, contributing to a more effective infrastructure management framework at Sopra Steria.
