The central management of multiple AWS accounts is accomplished through AWS Organizations. This service enables users to create and manage multiple AWS accounts from a single interface, allowing for greater control and oversight across an organization’s cloud resources. AWS Organizations allows administrators to group accounts into organizational units (OUs) and apply policies at both the organization and OU levels, which facilitates streamlined governance, billing, and security management.
AWS Organizations also provides features like consolidated billing, which helps in managing costs by merging multiple accounts into a single billing entity. This capability is important for organizations that need to manage budgets across different departments or projects while maintaining the flexibility of separate accounts for operational purposes.
The other services listed do not provide central management of multiple AWS accounts. AWS CloudTrail is primarily focused on governance, compliance, and auditing by logging API calls for AWS services, but does not manage accounts. The AWS Command Line Interface (CLI) is a tool for managing AWS services through commands in a terminal, but it does not provide account management functions. Amazon VPC (Virtual Private Cloud) is concerned with network isolation and does not deal with account management.
