Course content

1 section • 11 lectures • 4h 37m total length

  • Introduction to Networking23:50

    Explore how Azure virtual networks mirror on-premise LANs to enable lift-and-shift of apps, while detailing OSI layers, protocols like TCP/UDP, and the role of sockets, IP addresses, and ports.

  • Introduction to Networking
  • Introduction To VNet22:08

    Explore how a virtual network (VNet) provides an isolated boundary in Azure, organizing subnets, NSGs, VMs, and DNS, with connectivity to on-premise networks via VNet connections or ExpressRoute.

  • Introduction To VNet
  • Understanding IP Address space27:41

    Define a vnet address space with cidr notation to allocate private ip ranges. Assign public and private ips to the network interface card (nic), using static or dynamic options.

  • Understanding IP Address space
  • Creating VNet and Subnet16:12

    Create an azure virtual network in East US with two subnets (front end and back end) using 192.168.0.0/16 and 192.168.1.0/24, 192.168.2.0/24, within a new resource group Demo East US RG.

  • Creating VNet and Subnet
  • Creating NSG and Rules15:33

    Configure Azure network security groups for VNet subnets, attach front-end and back-end NSGs, and define inbound and outbound rules for RDP 3389, HTTP 80, and MySQL 1433 traffic.

  • Creating NSG and Rules
  • NSG Rules in Action24:02

    Demonstrates NSG rules in action within a two-subnet vnet by provisioning a Windows Server 2022 VM, enabling IIS, and validating port 80 and RDP access through the subnet NSGs.

  • NSG Rules in Action
  • Advanced NSG Features32:31

    Explore advanced NSG features by configuring NSGs on subnets and NICs, using effective security rules, and applying inbound and outbound rules with network watcher diagnostics.

  • Advanced NSG Features
  • Application Security Group18:06

    Use Azure application security groups to group web servers and database servers, simplify network security rules, and enforce traffic flow by denying web-to-database connections through group-based rules.

  • Application Security Group
  • Azure Bastion28:34

    Explore Azure Bastion to securely access virtual machines via RDP or SSH without exposing public IPs, using a VNet subnet, portal access, and SSL-based secure connections.

  • Azure Bastion
  • User-Defined Route Table37:34

    Explore Azure route tables, system and user-defined routes, and how virtual appliances with IP forwarding control outbound traffic and next hops across subnets, VNets, and on-premises.

  • User-Defined Route Table
  • Public and Private DNS Zone31:27

    Learn how DNS maps domain names to IPs via DNS servers and root servers, and configure public and private DNS zones in Azure virtual networks.

  • Public and Private DNS Zone

Requirements

  • Basic understanding of networking concepts is helpful
  • Familiarity with Microsoft Azure fundamentals is an advantage
  • No advanced Azure networking experience is required

Description

This course provides an in-depth and practical understanding of Azure Virtual Networks (VNet), one of the most critical building blocks of Azure infrastructure.

You will start with core networking fundamentals, ensuring a solid understanding of how networks function before moving into Azure-specific concepts. The course then introduces Azure Virtual Networks, explaining how VNets are designed, created, and managed within the Azure platform.

As you progress, you will explore IP address spaces and subnetting, learning how proper IP planning plays a key role in scalable and secure network design. You will then dive deep into Network Security Groups (NSGs), including rule creation, rule evaluation, and advanced NSG features that control inbound and outbound traffic.

The course also covers Application Security Groups (ASG), helping you simplify security management at scale. You will learn about Azure Bastion for secure VM access without exposing public IPs, as well as User-Defined Routes (UDR) to control traffic flow within your network.

In addition, you will understand how Public and Private DNS Zones work in Azure and how name resolution integrates with virtual networks.

Each topic is explained through focused video lessons designed to build both conceptual clarity and real-world understanding. By the end of this course, you will have a strong grasp of Azure Virtual Network design, security, and routing concepts that are essential for Azure administrators and cloud engineers.

Who this course is for:

  • Azure administrators and cloud engineers
  • IT professionals working with Azure infrastructure
  • Network administrators moving to Azure
  • Students learning Azure networking concepts
  • AZ-104 aspirants focusing on virtual networking
  • Anyone who wants a deep understanding of Azure VNets
