Overview
Industry: Retail – Convenience Stores
Geography: Global (U.S.-Headquartered)
Technologies: AWS Control Tower, Terraform, Security Hub, GuardDuty
The Situation
A leading U.S. convenience store chain had built its cloud infrastructure on AWS over several years. As global expansion accelerated, managing a growing number of AWS accounts each with its own configuration, access controls, and audit posture became a strategic liability.
The AWS environment had evolved organically into a flat, two-OU structure with no separation between production, sandbox, shared services, and security workloads. Account provisioning was manual, leading to inconsistent configurations, tagging gaps, and compliance blind spots. AWS Security Hub and GuardDuty were not uniformly deployed. Audit logs were scattered across accounts, making incident response and regulatory audit preparation slow and unreliable.
With global expansion on the roadmap, leadership needed assurance that every new AWS account would be provisioned securely, governed consistently, and audit-ready from day one.
What Codincity Did
Codincity deployed AWS Control Tower as the governance backbone, establishing a structured five-OU hierarchy Production, Non-Production, Sandbox, Shared Services, and Security each governed by preventive, detective, and proactive guardrails aligned to AWS best practices.
Automated account provisioning via Account Factory with Terraform, ensuring every new account inherits security guardrails, Service Control Policies, and governance baselines automatically.
AWS Security Hub and Amazon GuardDuty deployed uniformly across all accounts, activating more than 300 detective controls with centralised security findings in a dedicated audit account.
CloudTrail, AWS Config, and VPC Flow Logs centralised into a dedicated Log Archive account with long-term retention, streamlining audit and compliance workflows.
Entire Control Tower configuration SCPs, guardrails, and governance policies codified in Terraform for repeatable, version-controlled deployments.
Business Impact
Consistent governance policies enforced automatically across every AWS account, replacing error-prone manual processes.
Comprehensive, continuous security monitoring across the entire AWS estate through unified Security Hub and GuardDuty coverage.
Faster, reliable account provisioning new accounts onboard into a fully governed environment from day one, with no manual configuration required.
Streamlined audit and compliance response through centralised log aggregation and long-term retention.
A scalable cloud foundation that supports continued global growth without rebuilding governance as the estate expands.
What It Means Going Forward
The engagement fundamentally changed how the organisation manages its cloud environment. Teams no longer spend time on manual account setup or remediation they focus on building. Security has a single, unified view across every AWS account. And leadership has confidence that the cloud posture supports, rather than constrains, the company's global ambitions.
With Terraform codifying every governance decision, the platform is self-documenting and repeatable. As the business grows into new regions and launches new workloads, the governance foundation scales with it.
Conclusion
Effective cloud governance is not about adding more controls—it is about creating a foundation that enables the business to scale securely and consistently. By implementing AWS Control Tower, automating governance through Terraform, and centralizing security and compliance operations, Codincity helped the organization transform its AWS environment into a secure, standardized, and audit-ready platform. The result is a cloud foundation that supports continued global expansion while maintaining the visibility, control, and operational efficiency required at enterprise scale.
