Study Notes

Azure Storage and Blob Inventory

Azure Storage account can contain multiple containers, which store various types of data, such as image files.
An ARM template allows for the automation of creating resources, such as blob inventory rules.
Blob inventory rules can be configured to store specific data types based on naming conventions (e.g., only blobs starting with "finance") and can output data in formats like CSV.

Shared Access Signatures (SAS)

Shared Access Signatures (SAS) allow defined permissions for accessing specific resources within a storage account.
SAS can be generated for storage accounts and shared to allow temporary access without compromising the storage account's security.

Azure Kubernetes Service (AKS) Deployment

Azure CLI is used to manage Azure resources, including Azure Kubernetes Service (AKS).
To deploy configuration files (YAML), the kubectl command is appropriate; running az aks does not accomplish this.
AKS provides capability for application deployment; multiple solutions can exist for deploying configurations.

Azure Virtual Machine Monitoring and Alerts

Alerts can be set to monitor specific events in Azure Virtual Machines, such as logging error events in the System event log.
Backup policies for virtual machines require the Recovery Services vault to be in the same region as the virtual machines.

AKS Cluster Configuration

Autoscaling can be configured using the kubectl command to adjust the number of pods based on CPU utilization.
The az aks command can also be used for enabling and configuring cluster autoscaler for existing clusters.

High Availability Solutions

Deploying virtual machines across multiple Availability Zones ensures redundancy and availability in case a single datacenter fails.
Utilizing Availability Sets is beneficial for maintaining service continuity during hardware failures, but it does not protect against datacenter outages as effectively as Availability Zones do.

Azure Kubernetes Service and Virtual Machines

Azure Kubernetes Service (AKS) clusters can be deployed to manage containerized applications.
Commands like azcopy are not suitable for deploying YAML files in AKS. Correct approach involves using kubectl apply -f <filename>.yaml.

Alerting in Azure

Azure allows the creation of alerts when specific conditions are met, such as logging events in the System event log.
If more than two errors are recorded within an hour, an alert can be triggered.

Virtual Machine Scale Sets Deployment

Azure Virtual Machine Scale Sets (VMSS) enable deployment and management of multiple VMs that can scale based on demand.
Desired State Configuration (DSC) is utilized to ensure VMs have required configurations upon provisioning.
Actions needed for installing web server components include uploading configuration scripts and modifying the extensionProfile in the ARM template.

Resource Manager Templates

ARM templates define the infrastructure and configuration for Azure solutions.
Location of deployment can be specified in the resources section, overriding defined variables.
To change deployment location from "westeurope" to "westus," modify the location in the resources section.

App Service Plans

Staging slots are not available for all App Service plans; scaling up the App Service plan may be necessary to access this feature.

Availability and Fault Domains

Update Domains and Fault Domains help manage availability and VM resilience.
In a scenario with 14 VMs across 10 update domains, at most two VMs will be offline during updates.
With 2 fault domains, a rack failure could lead to 7 VMs offline.

Accessing Applications in AKS

To provide internet access to applications in an AKS cluster, a public IP address must be associated with the cluster.
For DNS records, a public IP address (e.g., 131.107.2.1) is required for internet users to access AKS-hosted applications.

Configuring Templates for Virtual Machines

When deploying a VM from a saved template, certain configurations can be set, including:
- Resource Group name and location
- Administrator username
Virtual machine configurations like OS size may not be adjustable at deployment from a template.

Scheduled Tasks for Performance Management

Scheduled runbooks can be created to manage VM settings based on usage patterns, such as increasing the processor performance of a VM during peak usage times at month-end.

Azure Configuration and Monitoring

Creating an Azure storage account with shared access signatures (SASs) does not meet the goal for monitoring VM activity.
Instead, set up an Azure Log Analytics workspace and configure data settings to enable effective monitoring.
Install the Microsoft Monitoring Agent on the virtual machine (VM1) for data collection.
Alerts in Azure Monitor should target the Log Analytics workspace rather than a storage account.

Virtual Machine Network Migration

VM1, residing in RG1 and connected to VNet1, cannot be directly moved to VNet2.
To transition the custom application to VNet2, delete VM1 while retaining its disk, then recreate VM1 in VNet2 and attach Disk1.
This method minimizes administrative effort while ensuring the application is migrated.

Secure Password Storage in Azure

Use Azure Key Vault to store administrative passwords securely instead of placing them in plain text in Azure Resource Manager templates.
Access policies for the Key Vault must be configured to allow appropriate access to the stored credentials.

Monitoring Resource Creation Dates

Viewing the creation date and time of resources in a resource group cannot be done via the Subscriptions blade.
Correct method to access resource creation details does not involve selecting resource providers, thus does not meet the goal.

Budget Alerts and Resource Management

Budget alerts for any resource group do not affect resource operations; they only trigger notifications.
For RG1, VM1 remains operational despite budget threshold alerts being reached, ensuring continuous resource availability.
Budget alerts are designed to provide notifications without stopping resource consumption.

Monitoring Linux Virtual Machines

For monitoring metrics and logs of a Linux VM (VM1), the Linux Diagnostic Extension (LAD) 3.0 is the appropriate tool.
Installing LAD ensures the collection of diagnostics and performance data from the Linux server, enabling effective monitoring.

Network Security for Web and DNS Server

Effective network security rules applied to VM1 determine its connectivity and security posture.
Understanding the effective network rules is crucial for maintaining security while running services like web and DNS servers on Azure.

Virtual Machine Scale Sets and Configuration

Virtual Machine Scale Sets (VMSS) allow for the deployment and management of numerous VMs that can automatically scale based on load.
Using the Azure Desired State Configuration (DSC) extension, VMs can be configured to install software, such as web server components, during provisioning.
To ensure VMs in a scale set have necessary components, upload a configuration script and modify the extensionProfile section of the Azure Resource Manager template.

Azure Kubernetes Service (AKS)

The command to install the kubectl client on a computer running Azure CLI is az aks install-cli.
This command allows for local management of AKS clusters using kubectl for automation and deployment of Kubernetes applications.

Azure Automation State Configuration Workflow

To manage and maintain virtual machine configurations through Azure Automation State Configuration, follow a specific sequence:
- Upload a configuration to Azure Automation State Configuration, importing into the Automation account.
- Compile the configuration into a node configuration, generating a Management Object Format (MOF) document.
- Assign the node configuration to the respective virtual machines.
Compliance status is checked regularly, and nodes report back to the pull server for status updates.

Azure Virtual Network Connection

Moving a VM to a different Resource Group and adding a new network interface does not allow switching between Virtual Networks (VNets).
To connect a VM (VM1) to a new VNet (VNET2), the VM must be deleted and recreated with the appropriate network interface.

Azure Alert Rule Configuration

When configuring alert rules, note the following:
- An alert triggered every minute results in one notification per minute for email.
- SMS notifications are limited to one every five minutes, totaling a maximum of 12 in an hour, ensuring manageable alert volumes.

Monitoring Linux Virtual Machines

To monitor metrics and logs on a Linux VM, the Linux Diagnostic Extension (LAD) 3.0 should be utilized.
LAD downloads the Diagnostic Extension Agent on Linux servers for effective monitoring.

Network Security Rules and VM Configuration

Understanding effective network security rules on VMs is crucial for managing access to services like web servers and DNS servers.
Specific configurations may impact how the VM communicates with networks and external entities.
