Which AWS service is designed for automating setups based on best practices?

The correct choice is AWS Control Tower, as it is specifically designed to help organizations set up and govern their multi-account AWS environments based on best practices recommended by AWS. AWS Control Tower provides a set of guardrails that help ensure compliance and best practice adherence while automating the creation of accounts. It simplifies the management of AWS organizations, streamlining the adoption of new AWS resources while ensuring security and compliance postures are maintained from the outset.

AWS Control Tower offers features such as centralized logging, account provisioning through a self-service interface, and compliance checks, making it an effective solution for enterprises aiming to implement AWS resources in a scalable and compliant manner. This proactive setup capability is essential for organizations looking to establish a robust governance framework right from the beginning of their AWS journey.

In contrast, while AWS CloudFormation is an efficient tool for automating infrastructure as code, it focuses on deploying specific resources rather than facilitating an entire multi-account setup with best practices. AWS OpsWorks is a configuration management service that helps deploy and manage applications but is not centered around best practices for account governance. AWS CodeDeploy automates application deployment to various compute services but does not inherently focus on overall account setups or governance.
