Understanding AWS Control Tower Architecture

Written by Zane White

AWS Control Tower is a service designed to simplify the setup and governance of secure, multi-account AWS environments. It leverages best practices developed through AWS’s extensive experience with enterprise cloud migrations. The service automates the creation of a baseline multi-account AWS environment that is secure, well-architected, and ready for immediate use.

AWS Control Tower utilizes AWS Organizations to create and manage new AWS accounts in a secure and compliant manner. It offers a pre-configured set of guardrails, which are rules for security, operations, and compliance that can be applied across an entire enterprise or to specific account groups. These guardrails help enforce policies and best practices throughout the AWS environment.

The service allows customers to establish their multi-account environment quickly through the AWS Management Console. It also provides a dashboard that offers visibility into the entire AWS environment and assists in policy enforcement for security, compliance, and operations. By streamlining the process of setting up and managing a multi-account AWS environment, AWS Control Tower helps organizations maintain consistency and adhere to best practices as they scale their cloud operations.

This helps customers enforce policies and best practices for security, compliance, and operations across their entire AWS environment.

Guardrails: Enforcing Policies and Best Practices

The third component of the AWS Control Tower architecture is Guardrails, which are a set of pre-packaged rules for security, operations, and compliance that customers can apply enterprise-wide or to specific groups of accounts. Guardrails help customers enforce policies and best practices for security, compliance, and operations across their entire AWS environment. They provide customers with a way to automate the enforcement of policies and best practices, making it easy for them to maintain a secure and compliant environment.

Understanding the Account Factory

The Account Factory is a key component of the AWS Control Tower architecture that is responsible for creating and managing new AWS accounts in a secure and compliant manner. It automates the process of setting up new accounts with the appropriate security and compliance settings, making it easy for customers to create new accounts that are ready to use. The Account Factory provides customers with a way to create new accounts with just a few clicks in the AWS Management Console, making it easy for them to set up new accounts that are secure and compliant.

The Account Factory also provides customers with a way to manage their existing accounts in a secure and compliant manner. It allows customers to apply policies and guardrails enterprise-wide or to specific groups of accounts, making it easy for them to enforce policies and best practices for security, compliance, and operations across their entire AWS environment. This helps customers maintain a secure and compliant environment by automating the enforcement of policies and best practices.

Overall, the Account Factory is an essential component of the AWS Control Tower architecture that provides customers with an easy way to create and manage new accounts in a secure and compliant manner. It automates the process of setting up new accounts with the appropriate security and compliance settings, making it easy for customers to create new accounts that are ready to use. It also provides customers with a way to manage their existing accounts in a secure and compliant manner, allowing them to enforce policies and best practices for security, compliance, and operations across their entire AWS environment.

Role of AWS Organizations in Control Tower

Metrics Description
Number of Organizational Units (OUs) The number of OUs created within AWS Organizations to organize and manage AWS accounts.
Number of Service Control Policies (SCPs) The number of SCPs applied to OUs to control permissions and access to AWS services.
Number of AWS accounts The total number of AWS accounts managed under AWS Organizations and Control Tower.
Compliance Score The overall compliance score of AWS accounts with the policies and guardrails set by Control Tower.

AWS Organizations plays a crucial role in the AWS Control Tower architecture by providing centralized management of all the accounts in the multi-account environment. It allows customers to create and manage the accounts in their environment in a secure and compliant manner, making it easy for them to apply policies and guardrails enterprise-wide or to specific groups of accounts. This helps customers enforce policies and best practices for security, compliance, and operations across their entire AWS environment.

AWS Organizations also provides customers with a way to automate the enforcement of policies and best practices by applying guardrails enterprise-wide or to specific groups of accounts. This makes it easy for customers to maintain a secure and compliant environment by automating the enforcement of policies and best practices. Overall, AWS Organizations is an essential component of the AWS Control Tower architecture that provides centralized management of all the accounts in the multi-account environment, making it easy for customers to apply policies and guardrails enterprise-wide or to specific groups of accounts.

Implementing Guardrails with AWS Control Tower

Guardrails are a set of pre-packaged rules for security, operations, and compliance that customers can apply enterprise-wide or to specific groups of accounts using AWS Control Tower. They help customers enforce policies and best practices for security, compliance, and operations across their entire AWS environment. Guardrails provide customers with a way to automate the enforcement of policies and best practices, making it easy for them to maintain a secure and compliant environment.

Customers can use guardrails to enforce policies such as requiring encryption at rest for Amazon S3 buckets or ensuring that all Amazon EC2 instances are launched within VPCs. They can also use guardrails to enforce best practices such as tagging resources with cost allocation tags or enabling CloudTrail logging for all API activity. Overall, guardrails provide customers with a way to automate the enforcement of policies and best practices, making it easy for them to maintain a secure and compliant environment.

Customers can also create custom guardrails using AWS Config rules or Service Control Policies (SCPs) to enforce specific policies or best practices that are unique to their organization. This allows customers to tailor their guardrails to meet their specific security, compliance, and operational requirements. Overall, guardrails are an essential component of the AWS Control Tower architecture that provides customers with a way to automate the enforcement of policies and best practices, making it easy for them to maintain a secure and compliant environment.

Managing Landing Zone with AWS Control Tower
