Azure is a cloud computing platform offered by Microsoft that provides a wide range of services to help organizations build, deploy, and manage applications and services through Microsoft-managed data centers. When using Azure, it is important to understand the difference between an Azure tenant and an Azure subscription. While they are related, they serve different purposes and have different functionalities.
An Azure tenant is a dedicated and isolated instance of the Azure Active Directory (Azure AD) service. It is a trust boundary that defines administrative boundaries for Azure resources and services. When you sign up for an Azure account, you are creating an Azure tenant. Each tenant is unique and has its own domain name, which is used for signing in to Azure services.
Within an Azure tenant, you can create and manage multiple subscriptions, each of which provides a logical unit of Azure resources. The tenant acts as a container for these subscriptions and allows you to manage access, policies, and security settings across them. It also provides a unified identity and access management system that allows you to control who has access to your Azure resources.
One of the key benefits of having an Azure tenant is that it allows you to manage multiple subscriptions under a single umbrella. This makes it easier to organize and manage your resources, as well as provide centralized authentication and authorization mechanisms.
An Azure subscription is a logical unit of resources that is billed separately. It provides access to Azure services and resources, such as virtual machines, storage accounts, and databases. When you sign up for an Azure account, you are given a default subscription, but you can create additional subscriptions within your Azure tenant if needed.
Each subscription has its own billing, usage, and resource limits. It also has its own set of administrators and access control policies, which can be managed at the subscription level. This allows you to have fine-grained control over who can access and manage the resources within a specific subscription.
Subscriptions are typically used to organize resources based on different departments, projects, or environments within an organization. They provide a way to allocate costs and track usage for specific sets of resources. Subscriptions also provide a level of isolation between resources, allowing you to enforce different security and compliance requirements.
