Portfolio Details

Planning, organization and support of multi-account, multi-customer, large-scale environments:

Project Overview:

Unified Techs was tasked with managing and supporting a complex AWS Account Organization comprising more than 100 individual AWS accounts (learn more about AWS Organizations). The client required a centralized governance model that could scale with their expanding cloud infrastructure while enforcing security, compliance, and cost control across departments and environments.

Before our engagement, account provisioning was manual, security policies were applied inconsistently, and operational visibility was limited. As a result, the client needed a solution to automate multi-account management and standardize controls across their AWS Account Organization.

Proposed Solution & Architecture:

Our team designed a scalable architecture using AWS Organizations to centrally manage and structure accounts under Organizational Units (OUs) tailored for development, staging, and production. We implemented AWS Control Tower to automate account provisioning and enforce baseline configurations through guardrails and Service Control Policies (SCPs).

To maintain secure and consistent access control, we configured IAM roles with permission boundaries, ensuring least-privilege access while preserving centralized oversight. Additionally, AWS CloudFormation StackSets deployed shared infrastructure, logging settings, and security baselines across all accounts from the central management account.

For visibility and compliance, we integrated AWS Config, AWS Security Hub, and AWS CloudTrail. These services provided a unified view of resource compliance, potential vulnerabilities, and user activity across the AWS Account Organization.

Key Enhancements:

• Centralized Management: Structured OUs and automated provisioning using AWS Control Tower simplified control of over 100 AWS accounts.

• Security & Governance: Enforced organization-wide SCPs, IAM policies, and centralized logging to strengthen security.

• Automated Deployments: Used AWS CloudFormation StackSets for rapid and consistent deployments at scale.

• Cost Optimization: Enabled consolidated billing and implemented AWS Budgets and Cost Explorer for financial insights.

• Compliance Monitoring: Leveraged AWS-native services to detect misconfigurations and ensure compliance.

• Ongoing Support: Provided continuous governance updates, monitoring, and architectural improvements.

Conclusion:

This solution delivered a robust, secure, and scalable AWS Account Organization capable of supporting the client’s growth while ensuring operational excellence. With centralized governance, automated provisioning, and continuous compliance monitoring, the client can now focus on innovation without sacrificing control or security.
