What is the AWS Control Tower?

At its core, AWS Control Tower is a service that allows organizations to quickly set up and govern secure, well-architected, multi-account AWS environments. It provides:

• A centralized dashboard for managing accounts.
• Applying guardrails.
• Enforcing policies.
• Ensuring compliance with industry standards and best practices.

Think of AWS Control Tower as a control center for your AWS universe. It empowers you to establish a landing zone — a secure, scalable, and compliant foundation for your multi-account environment. Within this landing zone, you can create new accounts, apply pre-defined blueprints, and automatically enforce guardrails to ensure your accounts adhere to your organization’s security and compliance policies.

Key Features and Benefits

1. Landing Zone Setup: AWS Control Tower simplifies the creation of a secure and compliant landing zone, eliminating the need for manual configuration and scripting.
2. Account Factory: Easily provision new AWS accounts within the landing zone, streamlining the onboarding process for new teams and projects.
3. Guardrails: Apply pre-defined or custom guardrails to enforce security and compliance policies across your accounts. Guardrails can prevent actions like creating resources in unsupported regions or disabling logging.
4. Preventive and Detective Controls: AWS Control Tower provides preventive controls (guardrails) to block non-compliant actions and detective controls (CloudTrail and Config) to monitor and audit account activity.
5. Dashboard and Reporting: A centralized dashboard provides visibility into your multi-account environment, allowing you to monitor account activity, guardrail compliance, and overall health.
6. Integration with AWS Organizations: AWS Control Tower integrates seamlessly with AWS Organizations, allowing you to manage organizational units (OUs), accounts, and policies from one place.

Extensibility: AWS Control Tower is not a one-size-fits-all solution. It’s a flexible tool you can customize and extend through AWS CloudFormation templates and AWS Service Catalog products, making you feel it can adapt to your needs and requirements.

AWS Control Tower is ideal for a variety of use cases, including:

• Enterprise Organizations: Large organizations with complex multi-account environments can leverage AWS Control Tower to centralize governance, enforce security and compliance, and streamline account management.
• Startups and Small Businesses: AWS Control Tower’s simplified account setup, automated guardrails, and centralized management can benefit even smaller organizations.
• Regulated Industries: Industries with strict compliance requirements, like finance and healthcare, can rely on AWS Control Tower to maintain a secure and compliant cloud environment.
• Development and Test Environments: AWS Control Tower enables you to quickly create isolated environments for development and testing, ensuring security and minimizing the risk of configuration drift.
