Glossary: an Agility organization is your main account. All of your instances belong to it, and it holds billing and instance creation.
An organization is your main account in Agility, and every instance must belong to one. One is created for you automatically when you sign up.
From the organization, organization admins create and upgrade instances, manage billing and the payment methods shared across instances, and decide who can create instances. You also control how users authenticate for the organization, such as single sign-on and MFA.
