Azure RBAC Roles & Azure AD Administrator Roles

How the roles are related?

Before, access to the resources are managed with the help of only three administrator roles namely- Account Administrator, Service Administrator, and Co-Administrator but later on RBAC was added. Hence, Azure RBAC is the latest authorization system providing fine-grained access management to Azure resources including various built-in roles, can be assigned at different scopes, and help you to create your own custom rules. Several Azure AD administrator roles are available to help you manage the resources in Azure AD like users, groups, and domains.

There are following types of roles:

  • Classic Subscription Administrator Roles- As stated above, there are three types of classic subscription administrator roles in Azure, they are- Account Administrator, Service Administrator, and Co-Administrator. They have full access to the Azure subscription and can manage resources with the help of Azure portal, Azure Resource Manager APIs as well as the classic deployment model APIs. After automatically setting up the signed up account used for Azure as both the Account and Service Administrator, extra Co-Administrators can be added (both the administrators have equal access of the users who have assigned the Owner role i.e. an Azure RBAC role at the subscription scope).

  • Azure RBAC Roles- It's an authorization system built on Azure Resource Manager that offers fine-grained access management to Azure resources, like compute and storage. There are over 70 built-in roles in which following are the fundamental RBAC roles- 

  1. Owner has full access to all resources and delegates access to others.
  2. Contributor can create as well as manage all types of Azure resources but can't grant access to others.
  3. Reader can view Azure resources.
  4. User Access Administrator can manage user access to Azure resources. 

      The other built-in roles helps in the management of specific Azure resources. 

  • Azure AD Administrator Roles- They are used to manage Azure AD resources in a directory like creating or editing users, assigning administrative roles to others, resetting user passwords, managing user licenses, and managing user domains. Few Azure AD administrator roles are:

  1. Global Administrator manages access to all administrative features in Azure AD as well as services and can reset the password for any user.
  2. User Administrator creates as well as manages all aspects of users and group.
  3. Billing Administrator can make purchases and manage subscription.

Most of the data connectors it uses to ingest data come with their own workbooks, but better insight can be obtained by simply looking into the data that is being ingested by using tables and visualizations, including bar and pie charts. You can also make your own workbook easily by using this data from the beginning instead of using the predefined templates.

The loaf balancer also offers an option of DirectServerReturn which if configured, can help in directing the traffic from the DBMS VM to the SAP application layer directly to the application layer without routing through the load balancer. But, if it isn't configured, then the return traffic to the SAP application layer is routed through the load balancer. You can also use Azure Load Balan
