AWS Organizations serves as a container for your AWS accounts and comes with a default organization root user.
It enables you to manage the permissions of your organization’s accounts, which are governed by Service Control Policies (SCPs).
SCPs allow you to restrict access to AWS resources and services for each individual account.
Organizational Units (OUs) are groups of accounts within an AWS organization.
They facilitate the management of accounts that share similar permissions.
The permission policy assigned to an OU applies to all accounts within that unit.
