Efficient Landing Zone Automation Streamlines Setup, Reducing Manual Work by 80% for a PSU

Solutions

• A multi-account structure with organizational units (OUs) has been introduced in their AWS organizations to streamline account management, enabling hierarchical organization for better policy enforcement, providing granular access controls, and simplifying cost tracking.  
• SCP (Service Control Policy) in AWS Control Tower has been configured in their organization to mandate specific tagging standards, ensuring consistent tagging practices for resource management and cost allocation.  
• Permission provisioning by implementing SSO in their AWS organization through the IAM identity center empowers organizations to finely control and secure access to resources, mitigating security risks and enforcing the principle of least privilege, reducing the risk of unauthorized access.  
• Logs Archive in AWS Control Tower has been leveraged so that their AWS organizations can easily access and analyze logs from a single location to multiple accounts, enabling efficient monitoring and troubleshooting. 
• Consolidated billing has been employed in the client’s account to streamline their billing process with a single payment from the payer account instead of managing separate bills for each AWS account. So, the payer account receives a comprehensive bill that includes the aggregated costs of all linked accounts.
