Chapter 9.2 - Creating and Managing Virtual Machines (Part 2)

Virtual Machine Architecture

• Resource Group
  • Virtual Network (VNet)
    • Subnet
      • VM
        • NIC
          • Private IP
          • Public IP
        • Disk
        • NSG

Demonstration

• Create a Linux VM
  • Use Azure Portal, Azure CLI, and PowerShell via the Cloud Shell in the Cloud Playground
• Configure Disks
  • Add a data disk to the VM
• Configure Networking
  • Select/Create a VNet, subnet, NIC, PIP, and NSG
• Install a Webserver
  • Install Nginx using custom data
• Open NSG for HTTP
  • Manage security rules for the VM

Use Cases

• Intended Purposes
  • Linux/Windows Compute
    • Deploy Linux/Windows virtual machines using Azure VM's IaaS model
  • Migrate Workloads
    • Migrate compute workloads to Azure. For example, move web servers to Azure VMs
  • Cloud Computing Solutions
    • Azure VM workloads with specific configurations and additional resources can provide solutions with high availability, fault tolerance, scalability, and elasticity

Exam Tips

• Key Components
  • CPU/Memory
    • Sizing determines CPU and memory
  • Networking
    • VMs use VNets, NICs, and NSGs to determine connectivity
  • Storage
    • VMs use Azure Disks to storage OS, non-persistent, and persistent data
• Bonus Tip
  • Security for VMs can be managed by opening ports on a NSG (Network Security Group)
