Amazon Web Services (AWS) offers extensive resources, services, and applications for a global customer base. A key aspect of adopting cloud services is creating a secure, well-organized environment. AWS Control Tower significantly streamlines this process, altering the AWS Landing Zone approach for customers. This blog explores AWS Control Tower, its features, and its impact on customers' Landing Zone experiences.
AWS Control Tower is a managed service that provides an automated and structured method to set up a multi-account AWS environment. It simplifies creating and managing AWS accounts and organizing them using AWS Organizations. In addition, AWS Control Tower establishes a well-architected baseline environment, adhering to best practices and ensuring consistent security and compliance across all accounts.
Setting up an AWS Landing Zone takes significant time and requires immense administrative effort to define the security and compliance rules, including account creation. AWS Control Tower revolutionizes the AWS Landing Zone approach by simplifying account creation and management. It automates setting up and organizing multi-account AWS environments and provides a single dashboard for monitoring and management. In addition, by implementing security and compliance best practices through predefined guardrails, AWS Control Tower ensures consistent security across all accounts and covers both preventive and detective controls.
Furthermore, AWS Control Tower integrates seamlessly with AWS Organizations, allowing customers to create organizational units (OUs) for efficient account grouping and management. This hierarchical structure simplifies resource management and enables centralized billing, making it easier for customers to track and optimize their cloud spend.
AWS Control Tower also provides a foundation for customization and extensibility, allowing customers to tailor their environments to their needs. For example, they can add new services, configure additional guardrails or integrate with third-party tools. In addition, by streamlining the AWS Landing Zone setup process, AWS Control Tower accelerates cloud adoption so that customers can focus on deploying and scaling their applications instead of spending time setting up infrastructure.
AWS Control Tower leverages several AWS services to deliver its streamlined multi-account management capabilities. Some of these services play essential roles in the AWS Control Tower environment, as outlined here:
Customizations for Control Tower
One of the key customization features for AWS Control Tower is the Customization for Control Tower (CfCT); it allows you to apply tailored governance, security, and compliance rules to your AWS Control Tower environment by integrating with AWS CloudFormation StackSets and AWS Organizations Service Control Policies (SCPs). The customized configuration has to be defined in a manifest file and can be triggered either as a source from S3 or via AWS CodeCommit. This solution offers you the advantages of programmatic management of your guardrails and reusability. Additionally, you can also manage this at a central location, reducing management overhead.
Account Factory Customization
Another powerful customization feature AWS Control Tower offers is the Account Factory Customization (AFC). This is a service that automates the process of creating new AWS accounts and applying baseline configurations. The underlying service is the AWS Service Catalog. With Account Factory Customization, you can modify the account creation process to suit your organization's specific requirements. Customers can create custom blueprints to specify configurations or resource creations. AWS Partners provide partner blueprints for Control Tower like DataDog with their integration blueprint.
A Greenfield environment refers to a new, uncharted territory where there are no pre-existing AWS accounts or resources. To set up AWS Control Tower in a Greenfield environment:
A Brownfield environment refers to an existing AWS environment with pre-configured accounts and resources. To enable AWS CT in a Brownfield environment, follow this steps:
AWS Control Tower has transformed the AWS Landing Zone approach for customers, providing a simplified, streamlined way to set up a secure, compliant, and well-architected multi-account AWS environment. By automating account creation and management, implementing security and compliance best practices, and integrating seamlessly with AWS Organizations, AWS Control Tower empowers customers to focus on their core business objectives and accelerate cloud adoption.
With these advanced customization options, AWS proactively responds to the needs of mature AWS Landing Zones users, providing them with the customizations they are familiar with from classic landing zone architectures. In the future, multi-tenant management of multiple AWS Control Tower Landing Zones would be desirable to provide better manageability of multiple AWS Control Tower environments for enterprise companies or MSPs.
