Study Notes
Azure Virtual Machine Storage Recommendations
- Adding a 1-TB data disk to VM1 requires a storage type ensuring data resiliency, low latency, and data protection from host failures.
Azure Key Vault and Disk Encryption
- For configuring Azure Disk Encryption, two necessary actions for Vault1 are selecting Azure Virtual Machines for deployment and creating a new key.
VM Encryption Methods
- To encrypt VM1 while meeting specific requirements, Azure Disk Encryption is the most effective method as it can store and use the encryption key in KV1, maintain encryption during VM downloads, and encrypt both the OS and data disks.
Shared Access Signature (SAS) Configuration
- To enable secure downloads of blobs in a storage account, configure a shared access signature (SAS) that restricts actions to downloading only by blob name.
Container Access Configuration
- To configure access for container1, a shared access signature (SAS) is required to allow read access, permit both HTTP and HTTPS protocols, and apply permissions to all container content.
Azure Storage Account Creation for Data Lake
- When creating an Azure Storage account (storage1) for Azure Data Lake, include zone-redundant storage (ZRS), the Cool access tier, and geo-redundant storage (GRS) to minimize costs for infrequently accessed data and enable automatic data replication.
Blob Versioning and Lifecycle Management
- Blob versioning allows snapshots of critical blobs within containers, alongside lifecycle management policies that can affect data retention and accessibility.
Storage Account Replication Options
- A storage account can be converted to zone-redundant storage (ZRS) replication under specific conditions, while other types of accounts may have limitations.
Azure Storage Explorer Installation
- Azure Storage Explorer can be installed on multiple devices, allowing users various options for accessing and managing Azure storage resources.
Deploying to Azure Kubernetes Service (AKS)
- To deploy a YAML file to an AKS cluster, the correct method is using the kubectl client through Azure CLI; other methods like az aks and azcopy do not meet the deployment requirements.
Azure Monitor Alerts Configuration
- For monitoring error events on VM1, utilize Azure Log Analytics workspace, not a storage account; this allows for alert creation based on error event thresholds within a designated timeframe.### Azure Virtual Machines Management
- Moving a virtual machine (VM) across virtual networks requires deleting the VM while retaining the disk, then recreating it in the target VNet.
- Admins can create and manage multiple virtual machines using the Azure Resource Manager templates.
Custom Applications in Azure
- To migrate an application between VNets, identify the disk used, delete the VM, and recreate it in the target network to minimize administrative effort.
Securing Administrative Passwords
- Use Azure Key Vault with an access policy to securely store administrative passwords, preventing their exposure in plain text within templates.
Azure App Service Plans
- ASP.NET Core apps can be hosted on both Windows and Linux platforms, while the ASP.NET apps are limited to Windows only.
- Current App Service plan tiers (Basic, Standard, Premium, Isolated) determine features like deployment slots.
Autoscale Configuration for Virtual Machine Scale Sets
- Autoscale rules allow automatic scaling of VMs; for example, scaling up from 4 to 6 VMs when CPU usage exceeds 80%.
- Scaling in can reduce VMs down to a minimum set, ensuring resource efficiency while maintaining performance.
Automating Virtual Machine Deployment
- To include web server components in scale set VMs, modify the extensionProfile section of the Resource Manager template and use Azure Desired State Configuration (DSC).
Installing Clients in Azure Kubernetes Service
- Use the command
az aks install-clito install the kubectl client on local machines for managing AKS clusters.
Azure Automation State Configuration
- Steps to manage VM configurations include uploading a configuration, compiling it into a node configuration, and assigning the configuration to ensure compliance.
Resource Manager Template Modifications
- To change the deployment location of a VM, modify the location in the resources section of the ARM template directly.
Deployment Slots in Azure Web Apps
- Creating a staging slot for an Azure web app requires the app to be in the Standard, Premium, or Isolated tier; scaling up the plan is necessary.
High Availability Strategies in Azure
- An Availability Set with multiple update domains is crucial for ensuring that a distributed application remains operational during planned maintenance, maximizing uptime.
Alerting in Azure
- To set alerts for error events on a VM, utilize Azure Log Analytics with the Microsoft Monitoring Agent, ensuring events are logged and monitored effectively.
VM Redeployment
- Moving a VM to a different host following a maintenance notification requires redeployment rather than a simple move within the Azure interface.### Redeploying Azure Virtual Machines
- To move an Azure VM to a different host and retain all configurations, use the Redeploy option from the Redeploy blade.
- Redeploying a VM involves moving it to a new node within the Azure infrastructure and powering it back on.
Network and Virtual Machines
- Azure VM connection to VNet: You cannot change the VNet associated with a VM after its creation. To connect a VM to a new VNet, delete and recreate the VM with the new network interface.
- Azure VNet: You can change the subnet of a VM but not the VNet itself.
Custom Domains for Azure Web Apps
- To add a custom domain (e.g., www.contoso.com) to an Azure Web App, start by creating the appropriate DNS record (CNAME or A record) to map the custom name.
Azure Resource Management
- When deploying multiple Azure Web Apps, only one App Service plan is required to minimize Azure costs, rather than creating separate plans for each app.
Azure Availability Sets
- When using an Availability Set, virtual machines shared across update domains can lead to only a specific number of VMs being offline during maintenance, controlled by the update domain count.
- Fault domains prevent total VM outage; in case of failure in one fault domain, not all VMs would be affected.
Azure Kubernetes Service (AKS)
- To allow internet users access to applications running in an Azure Kubernetes Service cluster, the appropriate public IP address should be configured in the DNS record.
Resource Quotas in Azure
- Azure regions have limits on regional vCPUs. Deallocated VMs count toward the total limit. For instance, if the regional quota is 20 vCPUs, and existing VMs are using 18, only 2 vCPUs remain available.
VM Changes and Downtime
- Resizing a VM (e.g., changing from D4s v3 to D8s v3) requires the VM to be stopped, resulting in downtime.
- Adding disks or extensions generally does not cause downtime.
Testing Application Updates
- To test updates of an application running on an Azure Web App, deploy the update to a testing slot, test it, and only then swap with the production slot for user access.
Monitoring VM Connection Attempts
- To record successful and failed connection attempts to an Azure VM, enable Azure Network Watcher in the appropriate region and utilize NSG flow logs for detailed monitoring.
