A multi-account AWS architecture designed for enterprise compliance and security. Uses Terraform for infrastructure-as-code with Service Control Policies (SCPs) for guardrails.
This landing zone pattern separates workloads into isolated accounts while centralizing audit logging and security controls.
The Challenge
Organizations need to balance developer agility with security compliance. A single AWS account becomes a security and blast radius risk as teams grow.
The goal was to create a reusable landing zone that enforces security best practices while allowing teams to work independently in isolated accounts.
Architecture Design
Implemented AWS Organizations with separate accounts for dev, staging, production, and audit. SCPs enforce guardrails like preventing public S3 buckets and requiring MFA.
All infrastructure is defined in Terraform with CI/CD gates that prevent non-compliant changes from reaching production.
Implementation Details
Account Structure
Organizational Units (OUs) separate workloads by environment. Cross-account roles enable centralized operations without compromising isolation.
Security Controls
SCPs prevent dangerous actions at the organization level. CloudTrail logs are centralized in a locked-down audit account.
Problems & Solutions
SCP Complexity
Results
The landing zone is production-ready and fully documented for reuse across organizations.
