Introduction to Azure Networking

Networking is at the core of every successful cloud solution, and Azure makes it possible to design secure, scalable, and highly available infrastructures with ease. In this video, we provide a comprehensive Introduction to Azure Networking, walking you through the essential components that power communication between applications, services, and users. Whether you are just starting your cloud journey or looking to refine your architecture, this session will give you the clarity and hands-on knowledge you need.

We start by answering the question Azure What is a Virtual Network (VNet) and demonstrate Azure Creating a Virtual Network step by step. From there, you will learn how Subnets in Azure VNet provide logical segmentation and why Azure VNet Peering is critical for building interconnected, distributed systems.

The video also explores connectivity and traffic distribution. You will discover how Azure Virtual Network Gateways support hybrid connectivity, how an Azure Load Balancer improves responsiveness, and the differences between an Azure Public Load Balancer and an Azure Internal Load Balancer (ILB). To take traffic management even further, we explain the power of Azure Application Gateway and its integrated Web Application Firewall.

Security is a major theme. You will gain a clear understanding of Azure What is a Network Security Group (NSG) and see practical steps for Azure Configuring NSG Rules. We also compare Azure Firewall vs NSG, highlighting when to use each and how they can complement each other for layered protection. To round it out, we cover Azure Monitoring Network Traffic, showing you the tools that provide real-time visibility and diagnostics.

Finally, we’ll share Best Practices for Azure Networking, ensuring that you not only know how these services work but also how to implement them effectively in real-world environments.

What you will learn in this video

By the end of this session, you will:

1. Understand the role of VNets and subnets in Azure networking
2. Learn how to configure VNet peering and gateways for hybrid scenarios
3. Explore load balancing options including Public, Internal, and Application Gateways
4. Configure and manage NSG rules for traffic filtering
5. Compare Azure Firewall and NSGs to design layered security
6. Monitor and troubleshoot traffic with Azure’s built-in tools
7. Apply best practices to build secure, scalable, and manageable networks

This video is designed to give you both theoretical knowledge and practical guidance so you can confidently build and secure your Azure networks.

What’s Next

This session is just the beginning of your Azure journey. Now that you’ve mastered networking, the next step is securing identity and access. In the following video Identity and Access Management with Azure Active Directory, we’ll explore how Azure AD empowers you to manage users, groups, and permissions seamlessly across your environment. Stay tuned for an in-depth look at how identity becomes the backbone of your cloud security strategy.
