In this lesson I get into details of Azure Virtual Networks and how to implement them. This is a jam-packed lesson with loads of hands-on stuff. I explain the characteristics of virtual networks and subnets. After explaining some concepts, we go hands-on in building an actual Azure virtual network with two subnets through the Azure portal. As a bonus I also show how to create virtual machines through the Azure portal. After creating the virtual machines in the virtual networks, I show how the Azure built-in DHCP and DNS works.

3. Module 2 – Lesson 2 – Implementing and managing virtual networks (Part 1)
Azure networking components
• Virtual networks (VNet) *
• Subnets
• Network Interface Cards (NICs)
• IP Address (Public and Private)
• Network Security Groups
• VNet DNS
• Azure DNS
• Azure Load Balancers
• Azure Application Gateway
• Azure Traffic Manager
• Routing
• Virtual Network Connectivity
• Virtual Network Gateway

4. Module 2 – Lesson 2 – Implementing and managing virtual networks (Part 1)
Overview of Azure Virtual Networks (VNets)
• Azure Virtual Networks (VNets):
• Core component of Azure networking
• Provides the Logical Boundary
• Defined by private IP Address Space
• Can have multiple Subnets. Must have at least one subnet
• VNets reside in Azure regions/locations (this cannot be changed once created)
• Provides IP addresses to Virtual Machines (VMs) – DHCP? – The lease is infinite unless VM is
stopped (deallocated)
• Provides Azure provided DNS services by default
• VMs can move between Subnets

5. Module 2 – Lesson 2 – Implementing and managing virtual networks (Part 1)
Overview of Azure Virtual Networks (VNets)
• Private IP address:
• 10.x.x.x
• 172.16.x.x – 172.31.x.x
• 192.168.x.x
• Should be planned properly. The rule of thumb is to not use something that is already being used
on-premises in case someday a hybrid connection is required

6. Module 2 – Lesson 2 – Implementing and managing virtual networks (Part 1)
What are we going to build
To create VNets you need the following information:
• VNet name
• Address space (in CIDR notation)
• Subscription
• Resource Group
• Location
• Subnet Name
• Subnet Address Space
• DDos Protection requirement
• Service Endpoints
