Azure Networking – Fundamentals

Training Info

This training is an engineering-first deep dive into the functional reality of Azure networking. The focus remains on architectural “deltas” between on-premises networking and Azure-native constructs, bypassing marketing overviews to address production-level implementation. It provides the technical foundation required to build, secure, and manage environments that are both performant and cost-efficient.


Delivery & Duration

Two primary formats are available to align with team expertise and project requirements. Both are delivered online (live) or in-person.

  • The 1-Day Fast-Track: Optimized for senior engineers and architects. Focus is placed on core architecture, security patterns, and high-impact “gotchas.”
  • The Multi-Day Implementation Intensive: Includes comprehensive hands-on labs, guided “sandbox” building, and a collaborative review of specific environment networking debt.
  • Modular Delivery: Options exist to split sessions into 4-hour blocks to minimize impact on operational duties.

Program Curriculum

Module 1: Azure Networking Foundations

  • Virtual Networks (VNets) & Subnets: Designing for scale and logical isolation.
  • IP Addressing & CIDR Planning: Preventing the most common cause of technical debt.
  • Data Transfer & Egress Cost Modeling: Understanding the financial impact of inter-region traffic and peering.
  • Azure DNS: Resolving “split-brain” DNS challenges in hybrid environments.
  • Outbound Connectivity: Strategic use of Public IPs vs. NAT Gateway for secure egress.

Module 2: Traffic Control & Zero-Trust Security

  • Network Security Groups (NSGs): Effective rule management and common pitfalls.
  • User-Defined Routes (UDRs): Gaining granular control over traffic flow and force-tunneling.
  • The Private Access Spectrum: Deep dive into Service Endpoints vs. Private Endpoints (Private Link).
  • Azure Firewall: Positioning, policy management, and cost-optimization.
  • Default versus custom Azure networking behavior and platform overrides.

Module 3: Modern Connectivity Patterns

  • VNet Peering: Managing regional/global peering and non-transitive behavior.
  • The Hub-and-Spoke Model: Designing a scalable “Landing Zone” backbone.
  • Hybrid Connectivity: Strategic choice between Site-to-Site VPN, Point-to-Site, and ExpressRoute.
  • Encryption in Transit: MACsec vs. IPsec vs. TLS across the Azure backbone.
  • Connectivity limitations: Understanding platform-level throughput and prefix limits.

Module 4: Availability, Management & Troubleshooting

  • Load Balancing: Choosing between Layer 4 (Azure Load Balancer) and Layer 7 (Application Gateway/Front Door).
  • Secure Management: Deploying Azure Bastion for “no-public-IP” administrative access.
  • Network Watcher: Utilizing Connection Troubleshoot, IP Flow Verify, and Packet Capture.
  • Structured Troubleshooting: A proven methodology for isolating connectivity issues in Azure.
  • Observability: Setting up flow logs and traffic analytics for Day-2 operations.

Key Takeaways

Participants will be equipped to:

  • Prevent Over-Provisioning: Design cost-effective networks that scale without requiring rework.
  • Manage Hidden Costs: Identify and mitigate unexpected data transfer and egress charges.
  • Secure by Default: Implement Private Link and NSG strategies that satisfy rigorous security audits.
  • Troubleshoot with Data: Use Azure-native tools to identify root causes in minutes rather than hours.
  • Bridge the Gap: Align traditional NetOps expertise with modern DevOps/Cloud Ops requirements.

Next Steps

Technical leads are available to adjust the depth of these modules based on current project requirements.

Both options go directly to tech personnel; no sales funnel, no account managers.
