Tenant, Subscription, Resource
1. Tenant
==Here AAD needs to be replaced with Entra ID. ==
A Tenant, as it relates to Azure, refers to a single instance of Azure Active Directory, or, as it is often called “Azure AD”. Azure AD is a key piece of Microsoft’s cloud platform as it provides a single place to manage users, groups and the permissions they hold in relation to applications published in Azure AD.

2. Subscription
A Subscription in Azure is a logical container into which any number of resources (Virtual Machines, Web Apps, Storage Accounts, etc) can be deployed. It can also be used for coarse-grained access control to these resources, though the correct approach these days is to leverage Role Based Access Control (RBAC) or Management Groups.
