What is Azure Subscription
A Windows Azure subscription grants you access to Windows Azure services and to the Windows Azure Platform Management Portal. It’s also called as an active agreement with Microsoft which is needed to provision resources in Microsoft Azure.
A Windows Azure subscription has two aspects:
- The Windows Azure account, through which resource usage is reported and services are billed.
- The subscription itself, which governs access to and use of the Windows Azure services that are subscribed to. The subscription holder manages services (Windows Azure , SQL Azure, Storage etc) through the Windows Azure Platform Management Portal
Azure subscription are managed using admin accounts . there are three types of admin accounts
| Administrative role | Limit | Description |
| Account Administrator (AA) | 1 per Azure account | This is the person who signed up for or bought Azure subscriptions, and is authorized to access the Account Center and perform various management tasks. These include being able to create subscriptions, cancel subscriptions, change the billing for a subscription, and change the Service Administrator. |
| Service Administrator (SA) | 1 per Azure subscription | This role is authorized to manage services in the Azure portal. By default, for a new subscription, the Account Administrator is also the Service Administrator. |
| Co-administrator (CA) in the Azure classic portal | 200 per subscription | This role has the same access privileges as the Service Administrator, but can’t change the association of subscriptions to Azure directories. |
Each Azure subscription is associated with one Azure Active Directory (AD) directory. Users, groups, and applications from that directory can manage resources in the Azure subscription. Assigning of these access rights are done through Azure portal, Azure command-line tools, and Azure Management APIs.This document emphasizes on managing rights through Azure Portal.
Resource hierarchy and access inheritance
· Each subscription in Azure belongs to only one directory. (But each directory can have more than one subscription.)
· Each resource group belongs to only one subscription.
· Each resource belongs to only one resource group.
To find the Default Directory the subscription is associated with, go to the Azure classic portal, select Settings > Subscriptions.
To view Azure billing information and manage subscriptions, you must sign in to the Account Center as the Account Administrator.
Click on the “ACCOUNT CENTER” to manage subscription
Click on the appropriate subscription type to create one.
Azure RBAC has three basic roles that apply to all resource types:
· Owner has full access to all resources including the right to delegate access to others.
· Contributor can create and manage all types of Azure resources but can’t grant access to others.
· Reader can view existing Azure resources.
Access Rights are granted by assigning the appropriate RBAC (Resource Based Access Control) role to users, groups, and applications at a certain scope. The scope of a role assignment can be a subscription, a resource group, or a single resource. A role assigned at a parent scope also grants access to the children contained within it. For example, a user with access to a resource group can manage all the resources it contains, like websites, virtual machines, and subnets.
Azure Role-Based Access Control (RBAC) enables fine-grained access management for Azure. Using RBAC, you can grant only the amount of access that users need to perform their jobs. Within each subscription, you can grant up to 2000 role assignments.
