What is AWS Control Tower?

AWS Control Tower is a managed service that automates setting up and governing a secure, compliant multi-account AWS environment.

What are guardrails in Control Tower?

Guardrails are policies — either preventive Service Control Policies or detective AWS Config rules — that enforce security and compliance standards across all accounts in the landing zone.

What is the Account Factory?

Account Factory is a Control Tower feature that automates provisioning new AWS accounts pre-configured with the organization's guardrails and baseline settings.

Is Control Tower the same as AWS Organizations?

No, Control Tower is built on top of AWS Organizations and adds automated governance, guardrails, and account provisioning on top of the basic multi-account structure Organizations provides.

Is AWS Control Tower free?

Control Tower itself has no additional charge, but you pay for the underlying AWS resources it provisions, such as CloudTrail, AWS Config, and S3 storage.

How does Control Tower compare to Azure Blueprints?

Both automate governed environment setup on their respective clouds, but Control Tower is centered on multi-account landing zones while Azure Blueprints focuses on packaging and deploying artifact templates within subscriptions.

Definition

AWS Control Tower is a managed service that automates the setup and governance of a secure, multi-account AWS environment based on best-practice landing zone blueprints.

Overview

Control Tower addresses a problem every growing AWS organization eventually faces: as teams provision more accounts for isolation and billing clarity, keeping consistent security baselines, logging, and access controls across all of them by hand becomes unmanageable. Control Tower automates the creation of a well-architected multi-account landing zone, provisioning a management account, a shared logging account, and a security audit account with sensible defaults for CloudTrail logging, AWS Config recording, and centralized identity via AWS IAM Identity Center. At the core of Control Tower are guardrails — preventive controls implemented as Service Control Policies that block non-compliant actions outright, and detective controls implemented as AWS Config rules that flag non-compliant resources after the fact. New accounts are provisioned through the Account Factory, which applies these guardrails automatically so every account in the organization starts from the same secure, compliant baseline rather than being configured ad hoc. Control Tower is built on top of AWS Organizations and AWS Config, effectively packaging a set of manual best practices — the kind an experienced cloud architect would otherwise implement by hand across dozens of accounts — into a guided, repeatable service. It occupies a similar governance role to Azure Blueprints on Microsoft's cloud, though the two differ in how they package and enforce policy. Organizations with more complex or custom governance needs than Control Tower's opinionated defaults often layer Landing Zone Accelerator or custom Terraform modules on top.
