====== Azure Core ======
  * Azure is composed of a number of different logical elements that have a container-contained relationship.
      * There is //Azure AD//, which is the top-level construct known as the //tenant.//
      * There are //management groups// that are contained in the tenant and can contain one or more subscriptions.
          * There is always the built-in //root management group//, but others can be created to create a hierarchy of management groups that can be six levels deep.'
      * Subscriptions are a billing unit.
      * Within subscriptions there can be one or more //resource groups//, which in turn contain the individual resources, like virtual machines.
  * **Resource Groups** are logical collections of resources that share the same lifecycle. They can also serve as a scope for permissions.

====== Purchasing Methods ======
Ways to buy Azure services.

  * Direct from Microsoft in the form of a **pay-as-you-go ((MOSP) Microsoft Online Services Program)** plan.
