Think of them as your billing and security boundary within the Azure ecosystem. Every Azure resource, from virtual machines to databases, is associated with a specific subscription. Subscriptions enable you to organize and manage your cloud resources, control costs, and enforce organizational policies.
Key functions include:
* **Billing:** Subscriptions serve as a billing unit. All resource usage within a subscription is aggregated, and you receive a single bill for those resources. Different departments or projects can use separate subscriptions to isolate costs, which simplifies cost tracking and chargebacks.
* **Access Control:** Azure uses Role-Based Access Control (RBAC) to manage permissions. You can grant users or groups specific roles (e.g., contributor, reader, owner) at the subscription level, which then applies to all resources within that subscription. This helps maintain a secure environment.
* **Resource Limits:** Subscriptions have resource limits and quotas, such as the number of virtual machines you can create. These are in place to prevent unintended resource consumption and ensure a level playing field for all Azure customers.
* **Management and Governance:** Azure Policy can be applied at the subscription level. Azure Policy helps you enforce organizational standards and assess compliance at scale. For instance, you could prevent the creation of VM's in specific regions at the subscription level.

Remember that the subscription is a primary boundary for RBAC. br *Resource Limits and Quotas*: Be aware of subscription-level limits on the number of resources you can create. Understand that these limits can be adjusted via support requests. Pay attention to questions around service limits and how subscriptions can affect resource availability.br *Management Groups*: A management group holds multiple subscriptions. If a question mentions organizing policies and compliance across multiple subscriptions, this is where they must be managed.br *Organization*: Think of Azure Subscriptions as a logical grouping of resources, allowing for easier management and cost tracking. Choose the subscription type according to your needs (e.g., free, pay-as-you-go, enterprise agreement). br *Scenarios*: Carefully analyze the given scenario. Determine if the proposed solution aligns with the best practices for organizing resources, managing access, and controlling costs at the subscription level. *Always read the scenario requirements and restrictions.* Some questions will trick you into selecting the incorrect subscription type by leaving out information. *Assume the persona of an Azure Architect* to pick the best answer.

It establishes a trusted relationship with Azure, allowing you to deploy and manage resources, *control access* to them, and *track your costs*.

They serve as a: br *Billing Boundary*: All the resources you use within a subscription are billed together. br *Access Control Boundary*: You use Azure RBAC (Role-Based Access Control) to manage access to resources within a subscription. br *Management Boundary*: Subscriptions help organize resources logically and administratively. They allow you to isolate workloads for development, testing, and production environments.', 'how_it_works_content': "Azure uses a hierarchical structure: br *Azure Account*: This is the top-level entity representing your overall presence in Azure. It is associated with a Microsoft Account or organizational account. br *Subscriptions*: An Azure account can have one or more subscriptions. Each subscription has its own: br *Resource Groups*: Containers that hold related resources for an application. br *Resources*: Individual services like virtual machines, databases, and storage accounts. br *Users/Groups*: Assigned roles for access control. br When you deploy a resource, you choose the subscription and resource group where it will reside. Charges for those resources are then accumulated within the subscription's billing cycle."}
