Resources, Resource Groups, and Subscriptions

Azure Resources - the basic building block of Azure, for example, VM, VNets, DB, and container, etc

Resource Groups - a folder structure in Azure in which you organize resources like databases, virtual machines, virtual networks, or almost any resource

Subscriptions - a billing unit within Azure; all resources under a subscription get billed to a single owner

• Multiple Subscriptions - possible to create multiple subscriptions to separate out billing
• Management Groups - a hierarchy of subscriptions; can have many subscriptions, and group them, and put those groups into other groups
