Lab 04 - Implement Virtual Networking

Student lab manual

Exercise scenario

Your global organization plans to implement virtual networks. These networks will be in East US, West Europe, and Southeast Asia. The immediate goal is to accomodate all the existing resources. However, the organization is in a growth phase and wants to ensure there is additional capacity for the growth.

Note: An interactive lab simulation is available that allows you to click through this lab at your own pace. You may find slight differences between the interactive simulation and the hosted lab, but the core concepts and ideas being demonstrated are the same.

Estimated time: 20 minutes

The CoreServicesVnet virtual network is deployed in the East US region. This virtual network will have the largest number of resources. It will have connectivity to on-premises networks through a VPN connection. This network will have web services, databases, and other systems that are key to the operations of the business. Shared services, such as domain controllers and DNS also will be located here. A large amount of growth is anticipated, so a large address space is necessary for this virtual network.

The ManufacturingVnet virtual network is deployed in the West Europe region, near the location of your organization's manufacturing facilities. This virtual network will contain systems for the operations of the manufacturing facilities. The organization is anticipating a large number of internal connected devices for their systems to retrieve data from, such as temperature, and will need an IP address space that it can expand into.

The ResearchVnet virtual network is deployed in the Southeast Asia region, near the location of the organization's research and development team. The research and development team uses this virtual network. The team has a small, stable set of resources that is not expected to grow. The team needs a small number of IP addresses for a few virtual machines for their work.

You will create the following resources:

Virtual Network	Region	Virtual network address space	Subnet	Subnet
CoreServicesVnet	East US	10.20.0.0/16
			GatewaySubnet	10.20.0.0/27
			SharedServicesSubnet	10.20.10.0/24
			DatabaseSubnet	10.20.20.0/24
			PublicWebServiceSubnet	10.20.30.0/24
ManufacturingVnet	West Europe	10.30.0.0/16
			ManufacturingSystemSubnet	10.30.10.0/24
			SensorSubnet1	10.30.20.0/24
			SensorSubnet2	10.30.21.0/24
			SensorSubnet3	10.30.22.0/24
ResearchVnet	Southeast Asia	10.40.0.0/16
			ResearchSystemSubnet	10.40.0.0/24

These virtual networks and subnets are structured in a way that accommodates existing resources yet allows for the projected growth. Let's create these virtual networks and subnets to lay the foundation for our networking infrastructure.

Did you know?: It is a good practice to avoid overlapping IP address ranges to reduce issues and simplify troubleshooting. Overlapping is a concern across the entire network, whether in the cloud or on-premises. Many organizations design an enterprise-wide IP addressing scheme to avoid overlapping and plan for future growth.

In this exercise, you will:

• Task 1: Create a resource group
• Task 2: Create the CoreServicesVnet virtual network and subnets
• Task 3: Create the ManufacturingVnet virtual network and subnets
• Task 4: Create the ResearchVnet virtual network and subnets
• Task 5: Verify the creation of VNets and Subnets

Task 1: Create a resource group

Create a resource group for all the resources in this lab.

1. Go to the Azure portal.

2. Search for and select Resource groups, then select + Create.

3. Create the resource group with these settings.

Tab	Option	Value
Basics	Resource group	az104-rg4
	Region	(US) East US
Tags	No changes required
Review + create	Review your settings and select Create

1. Refresh the Resource groups page, and verify that az104-rg4 appears in the list.

Task 2: Create the CoreServicesVnet virtual network and subnets

The organization plans a large amount of growth for core services. In this task, you will create the virtual network and the associated subnets to accomodate the existing resources and planned growth.

Create the CoreServicesVnet virtual network

1. Search for and select Virtual Networks.

   

2. Select Create on the Virtual networks page.

   

3. Use the information in the following table to create the CoreServicesVnet virtual network.

Tab	Option	Value
Basics	Resource Group	az104-rg1
	Name	CoreServicesVnet
	Region	(US) East US
IP Addresses	IPv4 address space	10.20.0.0/16

>**Note:** Remove or overwrite the default IP Address space.

4. Create the CoreServicesVnet subnets. To begin creating each subnet, select + Add subnet. To finish creating each subnet, select Add.

Subnet	Option	Value
GatewaySubnet	Subnet name	GatewaySubnet
	Subnet address range	10.20.0.0/27
SharedServicesSubnet	Subnet name	SharedServicesSubnet
	Subnet address range	10.20.10.0/24
DatabaseSubnet	Subnet name	DatabaseSubnet
	Subnet address range	10.20.20.0/24
PublicWebServiceSubnet	Subnet name	PublicWebServiceSubnet
	Subnet address range	10.20.30.0/24

1. To finish creating the CoreServicesVnet and its associated subnets, select Review + create.

2. Verify your configuration passed validation, and then select Create.

Task 3: Create the ManufacturingVnet virtual network and subnets

In this task, you will continue to create an additional virtual network and associated subnets. The organization anticipates growth for the manufacturing offices so the subnets are sized for the expected growth.

>**Note**: If you need help, use the detailed steps in Task 2. 

Tab	Option	Value
Basics	Resource Group	az104-rg1
	Name	ManufacturingVnet
	Region	(Europe) West Europe
IP Addresses	IPv4 address space	10.30.0.0/16

Subnet	Option	Value
ManufacturingSystemSubnet	Subnet name	ManufacturingSystemSubnet
	Subnet address range	10.30.10.0/24
SensorSubnet1	Subnet name	SensorSubnet1
	Subnet address range	10.30.20.0/24
SensorSubnet2	Subnet name	SensorSubnet2
	Subnet address range	10.30.21.0/24
SensorSubnet3	Subnet name	SensorSubnet3
	Subnet address range	10.30.22.0/24

Task 4: Create the ResearchVnet virtual network and subnets

In this task, you will create the final virtual network and associated subnet. The organization does not plan for growth and has limited needs for the research and development offices.

Note

: If you need help, use the detailed steps in Task 2.

Tab	Option	Value
Basics	Resource Group	az104-rg1
	Name	ResearchVnet
	Region	Southeast Asia
IP Addresses	IPv4 address space	10.40.0.0/16

Subnet	Option	Value
ResearchSystemSubnet	Subnet name	ResearchSystemSubnet
	Subnet address range	10.40.0.0/24

Task 5: Verify the creation of VNets and Subnets

In this task, you will validate that you have all the necessary virtual networks and subnets to meet the organization's requirements.

1. On the Azure portal home page, search for and select All resources.

2. Verify that the CoreServicesVnet, ManufacturingVnet, and ResearchVnet are listed.

3. Select CoreServicesVnet.

4. In CoreServicesVnet, under Settings, select Subnets.

5. In CoreServicesVnet | Subnets, verify that the subnets you created are listed, and that the IP address ranges are correct.

   

6. Repeat steps 3 - 5 for each VNet. Just remember to change the virtual network selection to ensure you verify all of them.

Congratulations! You have successfully created a resource group, three virtual networks, and associated subnets.
