To create an instance of Azure Application Insights namedaz400-38443478-mainand configure it to receive telemetry data from an Azure web app with the same name, you’ll need to follow these steps:

Create a Log Analytics Workspace:

Go to theAzure Portal.

Search for Log Analytics Workspaces and select Add.

Select a Subscription and either use an existing Resource Group or create a new one.

Provide a unique name for your Log Analytics workspace.

Choose the Region that is appropriate for you.

Review the settings and then selectCreate1.

Create an Azure Application Insights Instance:

In the Azure Portal, navigate to Application Insights.

Click on + Create.

Fill in the instance details, ensuring the name isaz400-38443478-main.

Link the instance to the Log Analytics workspace you created in the previous step.

Review and create the Application Insights instance2.

Configure the Azure Web App to Send Telemetry Data:

Go to the Azure Web Appaz400-38443478-main.

Under Monitoring, selectApplication Insights.

Choose to use an existing resource and select the Application Insights instance you created.

Follow the prompts to set up the connection, which may involve adding the appropriate SDK to your web app and configuring the connection string or instrumentation key.

Verify Telemetry Data Reception:

After setting up, send some test traffic to your web app.

Then, go to the Application Insights instance and check the Overview or Performance sections to see if telemetry data is being received.

Remember to replace placeholder names with the actual names of your resources where necessary. These steps will help you set up Azure Application Insights to monitor your web app effectively.

To ensure that your Azure Web App namedaz400-38443478-maincan retrieve secrets from an Azure Key Vault namedaz400-3844J478-kv1using a system managed identity with the principle of least privilege, follow these detailed steps:

Enable a System Managed Identity for the Azure Web App:

Navigate to the Azure Portal.

Go to the Azure Web Appaz400-38443478-main.

SelectIdentityunder theSettingssection.

In theSystem assignedtab, switch theStatustoOn.

ClickSaveto apply the changes.

Grant the Web App Access to the Key Vault:

Go to the Azure Key Vaultaz400-3844J478-kv1.

SelectAccess policiesunder theSettingssection.

Click onAdd Access Policy.

ChooseSecret permissionsand selectGetandList. This grants the app the ability to read secrets, adhering to the principle of least privilege.

Click onSelect principal, search for your Web App nameaz400-38443478-main, and select it.

ClickAddto add the policy.

Don’t forget to clickSaveto save the access policy changes.

Retrieve Secrets in the Web App Code:

In your Web App’s code, use the Azure SDK to retrieve the secrets.

For example, in a .NET application,you can use theAzure.IdentityandAzure.Security.KeyVault.Secretsnamespaces.

Utilize theDefaultAzureCredentialclass which will automatically use the system managed identity when running on Azure.

using Azure.Identity;

usingAzure.Security.KeyVault.Secrets;

var client = new SecretClient(new Uri("https://az400-3844J478-kv1.vault.azure.net/ "), new DefaultAzureCredential());

KeyVaultSecret secret = await client.GetSecretAsync("my-secret-name");

string secretValue =secret.Value;

Replace"my-secret-name"with the actual name of the secret you want to retrieve.

By following these steps, your Azure Web App will be able to securely retrieve secrets from the Azure Key Vault using a system managed identity, without needingto store credentials in the code, and adhering to the principle of least privilege. Remember to replace the placeholder names with the actual names of your Web App and Key Vault.

With the storage account ready, you can configure backs up in the web app or App Service.

Open the App Serviceaz400-11566895-main, which you want to protect, in the Azure Portal and browse to Settings > Backups. Click Configure and a Backup Configuration blade should appear.

Select the storage account.

Click + to create a private container. You could name this container after the web app or App Service.

Select the container.

If you want to schedule backups, then set Scheduled Backup to On and configure a schedule: every five hours

Select your retention. Note that 0 means never delete backups.

Decide if at least onebackup should always be retained.

Choose if any connected databases should be included in the web app backup.

Click Save to finalize the backup configuration.
