In this lab, you learn how to implement your organization’s governance plans. You learn how Azure policies can ensure operational decisions are enforced across the organization. You learn how to use resource tagging to improve reporting.
This lab requires an Azure subscription. Your subscription type may affect the availability of features in this lab. You may change the region, but the steps are written using **East US**.
Your organization's cloud footprint has grown considerably in the last year. During a recent audit, you discovered a substantial number of resources that do not have a defined owner, project, or cost center. In order to improve management of Azure resources in your organization, you decide to implement the following functionality:
There are several interactive lab simulations that you might find useful for this topic. The simulation lets you to click through a similar scenario at your own pace. There are differences between the interactive simulation and this lab, but many of the core concepts are the same. An Azure subscription is not required.
+ [Manage resource locks](https://mslearn.cloudguides.com/en-us/guides/AZ-900%20Exam%20Guide%20-%20Azure%20Fundamentals%20Exercise%2015). Add a resource lock and test to confirm.
+ [Create an Azure policy](https://mslearn.cloudguides.com/en-us/guides/AZ-900%20Exam%20Guide%20-%20Azure%20Fundamentals%20Exercise%2017). Create an Azure policy that restricts the location resources can be located. Create a new resource and ensure the policy is enforced.
+ [Manage governance via Azure policy](https://mslabs.cloudguides.com/guides/AZ-104%20Exam%20Guide%20-%20Microsoft%20Azure%20Administrator%20Exercise%203). Create and assign tags via the Azure portal. Create an Azure policy that requires tagging. Remediate non-compliant resources.
In this task, you will create and assign a tag to an Azure resource group via the Azure portal. Tags are a critical component of a governance strategy as outlined by the Microsoft Well-Architected Framework and Cloud Adoption Framework. Tags can allow you to quickly identify resource owners, sunset dates, group contacts, and other name/value pairs that your organization deems important. For this task, you assign a tag identifying the resource role ('Infra' for 'Infrastructure').
In this task, you will assign the built-in *Require a tag and its value on resources* policy to the resource group and evaluate the outcome. Azure Policy can be used to enforce configuration, and in this case, governance, to your Azure resources.
1. In the **Authoring** blade, select **Definitions**. Take a moment to browse through the list of [built-in policy definitions](https://learn.microsoft.com/azure/governance/policy/samples/built-in-policies) that are available for you to use. Notice you can also search for a definition.
>**Note**: You can assign policies on the management group, subscription, or resource group level. You also have the option of specifying exclusions, such as individual subscriptions, resource groups, or resources. In this scenario, we want the tag on all the resources in the resource group.
>**Note**: The **Assignment name** is automatically populated with the policy name you selected, but you can change it. The **Description** is optional. Notice you can disable the policy at any time.
>**Note**: Now you will verify that the new policy assignment is in effect by attempting to create an Azure Storage account in the resource group. You will create the storage account without adding the required tag.
1. Once you create the deployment, you should see the **Deployment failed** message in the **Notifications** list of the portal. From the **Notifications** list, navigate to the deployment overview and click the **Deployment failed. Click here for details** message to identify the reason for the failure.
>**Note**: By clicking the **Raw Error** tab, you can find more details about the error, including the name of the role definition **Require Cost Center tag with Default value**. The deployment failed because the storage account you attempted to create did not have a tag named **Cost Center** with its value set to **Default**.
In this task, we will use the new policy definition to remediate any non-compliant resources. In this scenario, we will make any child resources of a resource group inherit the **Cost Center** tag that was defined on the resource group.
1. In the **Authoring** section, click **Assignments**.
1. In the list of assignments, click the ellipsis icon in the row representing the **Require Cost Center tag with Default value** policy assignment and use the **Delete assignment** menu item to delete the assignment.
1. Click **Assign policy** and specify the **Scope** by clicking the ellipsis button and selecting the following values:
1. Click **Review + Create** and then click **Create**.
>**Note**: To verify that the new policy assignment is in effect, you will create another Azure storage account in the same resource group without explicitly adding the required tag.
1. On the **Basics** tab of the **Create storage account** blade, verify that you are using the Resource Group that the Policy was applied to and specify the following settings (leave others with their defaults) and click **Review**:
1. Select **Add** and complete the resource lock information. When finished select **Ok**.
| Setting | Value |
| --- | --- |
| Lock name | `rg-lock` |
| Lock type | **delete** (notice the selection for read-only) |
1. Navigate to the resource group **Overview** blade, and select **Delete resource group**.
1. In the **Enter resource group name to confirm deletion** textbox provide the resource group name, `rg-lock`. Notice you can copy and paste the resource group name.
1. Notice the warning: Deleting this resource group and its dependent resources is a permanent action and cannot be undone. Select **Delete**.
1. You should receive a notification denying the deletion.
If you are working with **your own subscription** take a minute to delete the lab resources. This will ensure resources are freed up and cost is minimized. The easiest way to delete the lab resources is to delete the lab resource group.
+ In the Azure portal, select the resource group, select **Delete the resource group**, **Enter resource group name**, and then click **Delete**.
+ Using Azure PowerShell, `Remove-AzResourceGroup -Name resourceGroupName`.
+ Using the CLI, `az group delete --name resourceGroupName`.
+ Azure tags are metadata that consists of a key-value pair. Tags describe a particular resource in your environment. In particular, tagging in Azure enables you to label your resources in a logical manne.
+ Azure Policy establishes conventions for resources. Policy definitions describe resource compliance conditions and the effect to take if a condition is met. A condition compares a resource property field or a value to a required value. There are many built-in policy definitions and you can customize the policies.
+ The Azure Policy remediation task feature is used to bring resources into compliance based on a definition and assignment. Resources that are non-compliant to a modify or deployIfNotExist definition assignment, can be brought into compliance using a remediation task.
+ You can configure a resource lock on a subscription, resource group, or resource. The lock can protect a resource from accidental user deletions and modifications. The lock overrides any user permissions.
+ Azure Policy is pre-deployment security practice. RBAC and resource locks are post-deployment security practice.
+ [Design an enterprise governance strategy](https://learn.microsoft.com/training/modules/enterprise-governance/). Use RBAC and Azure Policy to limit access to your Azure solutions, and determine which method is right for your security goals.
