Virtual Network

Create a virtual network using the Azure portal

This quickstart guides you through creating a virtual network using the Azure portal. You'll then set up two virtual machines (VMs) within the network, deploy Azure Bastion for secure internet-based VM access, and enable private communication between the VMs.

Prerequisites: - An active Azure subscription. If you don't have one, you can create a free account.

Sign in to Azure: - Use your Azure account to access the Azure portal.

Create Virtual Machines          

Follow these steps to create two virtual machines, named vm-1 and vm-2, within the virtual network:

1. In the Azure portal, search for and select Virtual machines.

2. On the Virtual Machines page, click + Create, then select Azure virtual machine.

3. In the Basics tab of the Create a Virtual Machine page, enter or select the necessary details.

4. Move to the Networking tab and provide the required information.

5. Leave the remaining settings as defaults, and click Review + Create.

6. Review the settings, and select Create.

7. Once the first virtual machine is deployed, repeat these steps to create a second virtual machine with the same settings.

Connect to a Virtual Machine          

Follow these steps to connect to vm-1:

1. In the Azure portal, search for and select Virtual machines.

2. On the Virtual Machines page, choose vm-1.

3. In the Overview section of vm-1, click Connect.

4. On the Connect to Virtual Machine page, go to the Bastion tab.

5. Select Use Bastion.

6. Enter the username and password you set when creating the VM, then click Connect.

Create a virtual network using PowerShell

Delete a Virtual Network          

You can only delete a virtual network if no resources are connected to it. If there are resources linked to any subnet within the virtual network, you must first remove those resources. The steps for deleting a resource depend on its type. To learn how to delete resources connected to subnets, refer to the documentation for each specific resource type you wish to remove. Here’s how to delete a virtual network:

Delete a Virtual Network Using the Azure Portal

1. In the search box at the top of the portal, type Virtual Networks and select it from the search results.

2. From the list of virtual networks, choose the one you want to delete.

3. Verify that there are no connected devices by selecting Connected devices under Settings. If any devices are connected, you must delete them before proceeding with the virtual network deletion. If there are no connected devices, go to the Overview tab.

4. Click Delete.

5. To confirm the deletion of the virtual network, select Yes.
