Which service provides a straightforward way to govern a multi-account AWS environment?

AWS Control Tower is designed to simplify the governance of a multi-account AWS environment. It provides an easy and automated approach to set up and manage that environment by establishing best practices and implementing guardrails. With AWS Control Tower, organizations can create a multi-account structure that adheres to AWS best security and compliance standards, accelerating the implementation of AWS services across different accounts effectively.

The service includes capabilities such as centralized logging, account provisioning, and monitoring compliance with policies across all accounts. This allows administrators to maintain visibility and control over their AWS resources, ensuring that all accounts are consistently following the organization's governance policies. AWS Control Tower makes it straightforward to maintain compliance and best practices, which is particularly valuable for organizations with complex multi-account architectures.

Other services like AWS Config and AWS Service Catalog have different focuses—Config primarily deals with resource compliance and tracking changes within single accounts rather than multi-account governance, while Service Catalog is oriented towards managing and deploying AWS resources rather than overarching governance requirements. Lambda@Edge is a service linked to content delivery network management with CloudFront and does not relate to account management or governance.
