Case Study

Industry: Retail (Global Operations)

Organisation Size: 15,000+ employees

RCS Role: Senior Azure & DevOps Delivery Partner

Microsoft Platform: Azure Landing Zones | Azure Management Groups | Azure Policy | Terraform | Azure DevOps

A global retail organisation needed to migrate thousands of servers into Azure across multiple geographic regions.

Governance models and security controls varied between business units, creating operational inconsistency, architectural drift, and increased risk during migration.

The organisation required a standardised, enterprise-grade Azure landing zone architecture that could support global scale while maintaining governance, visibility, and security consistency.

RCS co-led discovery and design workshops to define business, security, and operational requirements across regions.

The outcome was a standardised enterprise Azure landing zone aligned to Microsoft Cloud Adoption Framework principles.

Key elements included:

• Design of a structured Azure Management Group hierarchy
• Codified Azure Policy framework for consistent governance enforcement
• Infrastructure-as-Code pipelines using Terraform for repeatable deployments
• Network segmentation and security controls embedded into the core architecture
• Regional consistency through templated deployment models

Security and governance controls were embedded into the platform foundation rather than applied post-migration.

The organisation established a governed Azure platform capable of supporting global retail operations at scale.

• Improved operational consistency across regions
• Standardised governance and policy enforcement
• Increased visibility into security posture
• Reduced architectural drift during cloud adoption
• Scalable foundation for continued digital expansion

The result was a unified, enterprise-ready Azure platform designed to support long-term growth without increasing security or operational complexity.

• Standardised landing zone deployed across multiple global regions
• Policy enforcement codified through Infrastructure-as-Code
• Reduced configuration drift across business units
• Improved governance visibility at enterprise scale

RCS designs Microsoft-aligned Azure landing zone architectures that embed governance, security, and automation at enterprise scale.
