Overview of an OU
What Is an OU?
An organizational unit (OU) is a container or a logical grouping of accounts in your organization. You can use OUs to group accounts together to administer them as a single unit. An OU can be mapped to a department, a subsidiary, or a project team. You can create OUs within other OUs. Each OU can have only one parent OU, but they can have many other child OUs or member accounts.
