  • Compute-optimized: High CPU, low memory
  • Memory-optimized: High memory, low CPU
  • Storage-optimized: High disk storage
• VM deployment:
  • Image-based deployment
  • Template-based deployment
  • Azure Resource Manager (ARM) templates
• VM management:
  • Start/stop/restart VMs
  • Configure VM settings (e.g., IP address, DNS)
  • Monitor VM performance and health

Azure Networking

• Virtual Network (VNet):
  • Isolated, secure network for Azure resources
  • Supports IPv4 and IPv6
  • Subnetting and routing
• Subnets:
  • Divisions of a VNet for organizational purposes
  • Can be used for security and access control
• Network Security Group (NSG):
  • Firewall rules for incoming and outgoing traffic
  • Can be associated with VMs and subnets
• Load Balancing:
  • Distributes traffic across multiple VMs
  • Supports HTTP, HTTPS, and TCP protocols

Monitoring And Troubleshooting

• Azure Monitor:
  • Collects data from Azure resources
  • Provides metrics, logs, and alerts
• Azure Log Analytics:
  • Centralized log collection and analysis
  • Supports querying and alerting
• Azure Advisor:
  • Provides recommendations for optimization and security
  • Supports cost estimation and resource utilization
• Troubleshooting tools:
  • Azure Network Watcher
  • Azure Storage Explorer

Azure Active Directory

• Azure AD:
  • Cloud-based identity and access management
  • Supports SSO, MFA, and conditional access
• Azure AD roles:
  • Global administrator
  • Azure AD administrator
  • Azure AD user administrator
• Azure AD security:
  • Passwordless authentication
  • Advanced threat protection
  • Conditional access policies

Storage Accounts

• Types of Storage Accounts:
  • General-purpose v1 (GPv1)
  • General-purpose v2 (GPv2)
  • Block blob storage
  • File storage
• Storage Services:
  • Blob storage (objects and files)
  • File storage (SMB shares)
  • Queue storage (message queues)
  • Table storage (NoSQL database)
• Storage Security:
  • Encryption at rest and in transit
  • Access control lists (ACLs)
  • Storage account keys and shared access signatures (SAS)

Virtual Machines

• A-series VMs are for general-purpose computing
• D-series VMs are storage optimized
• F-series VMs are compute optimized
• G-series VMs are memory optimized
• H-series VMs are for high-performance computing
• VM sizes include general-purpose, compute-optimized, memory-optimized, and storage-optimized
• VM sizes are categorized based on CPU, memory, and storage capacity

VM Deployment

• Image-based deployment involves creating a VM from an image
• Template-based deployment involves creating a VM from a template
• Azure Resource Manager (ARM) templates can be used for deployment

VM Management

• VMs can be started, stopped, and restarted
• VM settings can be configured, including IP address and DNS
• VM performance and health can be monitored

Azure Networking
