Troubleshooting Microsoft Azure Connectivity course

Here's a structured approach to learning and troubleshooting Azure networking based on the topics you've outlined:

1. Understanding Azure Networking Fundamentals

   • Familiarize yourself with the basic components and services of Azure networking.
   • Understand the Azure virtual network (VNet), subnets, network security groups (NSGs), and gateways.
   • Learn about Azure's DNS service, express routes, and site-to-site VPNs.

2. Setting Up and Troubleshooting VPN Gateways

   • Start by understanding the different types of VPNs (Point-to-Site, Site-to-Site).
   • Set up a VPN Gateway and validate its functionality.

3. Configuring and Securing Network Resources

   • Work with NSGs to control inbound and outbound traffic.
   • Learn to configure route tables and use user-defined routes (UDRs) for traffic control.
   • Understand and implement forced tunneling if needed.

4. Implementing Azure Firewall

   • Set up the Azure Firewall and create rules to manage traffic flow.
   • Troubleshoot any issues with rule configurations or Azure Firewall Manager settings.

5. Handling Traffic and Load Balancing

   • Configure a load balancer to distribute incoming network traffic across VM instances.
   • Troubleshoot issues related to load balancing, including health checks and traffic distribution rules.

6. Using Azure Bastion and JIT RBAC

   • Deploy Azure Bastion for secure in-browser RDP access to VMs.
   • Configure and troubleshoot Just-In-Time (JIT) VM access policies.

7. Performance and Latency Issues

   • Diagnose latency issues between on-premises networks and Azure VMs.
   • Ensure the network setup meets the performance SLAs.

8. Routing and Traffic Control

   • Understand and configure BGP for your VNet.
   • Troubleshoot issues with routing, including asymmetric routing.

9. Leveraging Azure Traffic Manager

   • Set up and manage Traffic Manager profiles to load-balance client traffic across global Azure regions.

10. Advanced Scenarios and Troubleshooting

    • Experiment with more complex scenarios involving multiple VNets, peering, service chaining, and so on.
    • Troubleshoot issues related to network redundancy, failover mechanisms, and disaster recovery scenarios.

11. Cleanup and Decommissioning

    • Once you've completed your troubleshooting exercises, clean up the resources you've created to avoid unnecessary costs.

12. Where Do I Go From Here?

    • After completing these topics, consider specializing further in specific areas like advanced networking, Azure security, or performance optimization.
    • Stay updated with Azure service updates and best practices.
    • Engage with the Azure community for real-world troubleshooting experiences and peer learning.

13. BONUS Lecture

    • This could be a review of all the topics covered, an introduction to new Azure networking features, or even a discussion on how to prepare for Azure networking certifications (e.g., Microsoft Certified: Azure Fundamentals). By following this structured approach, you'll build a strong foundation in Azure networking, enabling you to effectively troubleshoot and optimize network performance within the Azure ecosystem. Remember that hands-on practice is crucial, so try to implement these concepts in real-world scenarios as much as possible.
