Virtual Network

Lab Overview

In this lab, we will learn how to get started with on Azure to deploy your IaaS resources. We will create a virtual network (vNet) in Azure. We will then add two subnets in the lab and add two virtual machines, one in each subnet.

It is expected you have access to Azure portal and have an account and subscription created on Azure.

Create a virtual network

1. To access the Azure portal, go to http://portal.azure.com

2. Click on Create a resource > Networking > Virtual Network

3. In Create virtual network, enter or select this information:

   Setting	Value
   Subscription	Select your subscription
   Resource group	Select Create new, enter rg-lab, then select OK
   Name	Enter vnet1
   Region	Select (US) West US 2

4. Click Next: IP Addresses

   Setting	Value
   IPv4 address space	Enter 10.1.0.0/16

5. Click +Add subnet

   Setting	Value
   Subnet-name	Enter vnet1-subnet1
   Subnet - Address range	Enter 10.1.1.0/24

6. Click Add

7. Repeat steps 4 and 5 to add one more subnet as below:

   Setting	Value
   Subnet-name	Enter vnet1-subnet2
   Subnet - Address range	Enter 10.1.2.0/24

8. Leave the rest as default and select Review + Create. Review the values. Your output should look like this:

   

9. Click Create

10. Once the deployment is complete, go to the search bar at the top and type ‘Virtual Networks’ (G+/). Select Virtual Networks in the search results. You should see vnet1 show up in the list.

    

Create virtual machines

Create a virtual machine in the virtual network.

Create the first VM

1. On the upper-left side of the screen, select Create a resource > Compute > Virtual Machine

2. In Create a virtual machine - Basics, enter or select this information:

   PROJECT DETAILS

   Setting	Value
   Subscription	Select your subscription.
   Resource group	Select rg-lab. You created this in the previous section.

   INSTANCE DETAILS

   Setting	Value
   Virtual machine name	Enter vnet1-vm-mgmt1
   Region	Select West US 2
   Availability options	Leave the default No infrastructure redundancy required
   Image	Leave the default Ubuntu Server 18.04 LTS
   Size	Leave the default Standard DS2 v3

   ADMINISTRATOR ACCOUNT

   Setting	Value
   Username	Enter a user name of your choosing
   Password	Enter a password of your choosing. The password must be at least 12 characters long and meet the defined complexity requirements.
   Confirm Password	Reenter password

   INBOUND PORT RULES

   Setting	Value
   Public inbound ports	None

3. Select Next : Disks

4. In Create a virtual machine - Disks, leave the defaults and select Next : Networking

5. In Create a virtual machine - network-conceptsing, select this information:

   Setting	Value
   Virtual network	Leave the default vnet1
   Subnet	Leave the default vnet1-subnet1 (10.1.1.0/24)
   Public IP	Leave the default (new) vnet1-vm-mgmt1-ip
   Public inbound ports	Select Allow selected ports
   Select inbound ports	Select HTTP and SSH

6. Select Review + create. You’re taken to the Review + create page where Azure validates your configuration.

7. When you see the Validation passed message, select Create.

8. Once the deployment is complete, click Go to resource. This will take you to the VM overview page. Verify the VM status shows as Running.

Create a second virtual machine

Repeat the above steps to spin up a second virtual machine with the following configuration:

Setting	Value
Instance name	vnet1-vm-web1
Subnet	vnet1
Subnet	vnet1-subnet2
Public Inbound ports	SSH, HTTP

Keep the rest of the parameters default and create the virtual machine.

Install web server on virtual machine vnet1-vm-web1

Connect to the virtual machine.

1. Search virtual machines in the Search bar in the portal

2. Select the virtual machine vnet1-vm-web1

3. Go to the Overview page

4. Copy the public IP address of the VM

5. From your laptop terminal, run command:

   ssh <username>@<Public_IP_of_the_VM>
   

6. Install apache2 on the server

   sudo apt-get -y update
   sudo apt-get -y install apache2
   

7. Verify the service is running on the server. You should see a status of active (running) in the output:

   sudo service apache2 status
   

8. When done, type exit to leave the SSH session.

View the web server in action

Use a web browser of your choice to view the default welcome page. Type the public IP address of the VM as the web address. The public IP address can be found on the VM overview page or as part of the SSH connection string you used earlier.

Verify the web page loads successfully.

Next

In the next lab we will create Network Security Groups to control traffic via layer 4 ACLs.
