Azure Active Directory (AAD) provides a hosted Active Directory that is a scalable and convenient way to manage users for any application. The ability to easily link an AAD with your organization's Single-Sign-On (SSO) provider is a tremendous benefit. Since most organizations have Office 365 online, by default they have an Azure AD instance. As an operator, by linking the Azure AD to Kubernetes RBAC, you don't have to worry about off-boarding people and, as an app owner, you can easily assign members to Azure AD groups.

To start, we need to create Azure AD applications to link to our Kubernetes cluster. The steps we are going to follow are pretty much verbatim from https://docs.microsoft.com/en-us/azure/aks/aad-integration.
