Control Tower is designed to manage multi-account environments by providing an automated way to set up a baseline environment with governance and compliance checks against best practices. While it incorporates elements of account management and identity services, it is distinct in providing automated orchestration for a secure and compliant multi-account setup. Organizations is primarily for account management and billing aggregation, does not automate the setup of a secure environment. Identity and Access Management is critical for defining users and permissions, but does not govern multi-account structures. Security Hub focuses on compiling security findings and does not manage account setup or enforce compliance policies.
