This article provides a step-by-step guide on how to set up an Azure Virtual Network. Whether you are new to Azure or looking to expand your cloud networking knowledge, this guide will help you get started.
Prerequisites
Before you begin, make sure you have the following prerequisites:
- An Azure account
- Azure CLI installed on your machine
- Azure CLI context configured with your subscription
Step-by-Step Guide
1. Create a Resource Group
First, you need to create a resource group. A resource group is a container that holds related resources for an Azure solution.
az group create --name <ResourceGroupName> --location <Location>
Replace <ResourceGroupName> with a name for your resource group and <Location> with the Azure region where you want to create the resource group.
2. Create a Virtual Network
Next, create a virtual network. A virtual network is a logical grouping of IP subnets and other related network resources.
az network vnet create --resource-group <ResourceGroupName> --name <VNetName> --address-prefixes <AddressPrefix1> <AddressPrefix2> --subnet-name <SubnetName1> --subnet-prefix <SubnetPrefix1> --subnet-name <SubnetName2> --subnet-prefix <SubnetPrefix2>
Replace <ResourceGroupName>, <VNetName>, <AddressPrefix1>, <AddressPrefix2>, <SubnetName1>, <SubnetPrefix1>, <SubnetName2>, and <SubnetPrefix2> with appropriate values for your virtual network.
3. Configure Subnets
Subnets are used to divide a virtual network into smaller, more manageable segments. In the previous step, you created two subnets. You can configure additional subnets as needed.
az network vnet subnet create --resource-group <ResourceGroupName> --vnet-name <VNetName> --name <SubnetName> --address-prefix <SubnetPrefix>
Replace <ResourceGroupName>, <VNetName>, <SubnetName>, and <SubnetPrefix> with appropriate values for your subnet.
4. Configure DNS Servers
You can configure DNS servers for your virtual network. This step is optional, but it is recommended to have a DNS server configured for your virtual network.
az network vnet subnet update --resource-group <ResourceGroupName> --vnet-name <VNetName> --name <SubnetName> --dns-server <DNS1> <DNS2>
Replace <ResourceGroupName>, <VNetName>, <SubnetName>, <DNS1>, and <DNS2> with appropriate values for your DNS servers.
5. Verify the Virtual Network
After you have created the virtual network, you can verify that it was created successfully.
az network vnet show --resource-group <ResourceGroupName> --name <VNetName>
Replace <ResourceGroupName> and <VNetName> with appropriate values for your virtual network.
Conclusion
Congratulations! You have successfully set up an Azure Virtual Network. This guide provides a basic overview of the process, but there are many more advanced features and configurations available. For more information, please refer to the Azure Virtual Network documentation.
