Subscription

Used to create and use Azure services
Created for you when you sign up
📝 Logical container used to provision resources in Azure such as virtual machines, databases and more.
📝 When you create an Azure resource like a VM, you identify the subscription it belongs to
- As you use the VM, the usage of the VM is aggregated and billed monthly.
📝 Each subscription is a separate entity that can't be merged.

You can create new subscriptions to separate e.g.
- Environments
  - E.g. for testing, security, or to isolate data for compliance reasons.
  - 💡Useful because resource access control occurs at the subscription level.
- Organizational structures
  - E.g. limit a team to lower-cost resources & allow IT department a full range
  - 💡Allows you to manage and control access to the resources that users provision within each subscription
- Billing
  - Costs are first aggregated at the subscription level
    - Manage and track costs based on your needs
  - E.g. for production, development, testing
Or due to subscription limits:
- Subscriptions are bound to some hard limitations
  - E.g. the maximum number of Express Route circuits per subscription is 10

You'll receive a monthly invoice with payment instructions provided
- You also can get set up for multiple invoices.
Customize billing
- Allows you to e.g. have single invoice for organization but organize charges by department, team, or project.
- Billing structure:
  - Each billing account has billing profile
    - Each billing profile has different invoice sections
      - Each invoice section can be coupled to different subscriptions.
        
        Each invoice section is a line item on the invoice that shows the charges incurred that month
