PART 3 : MICROSOFT AZURE CREATING AND ADMINISTERING VIRTUAL NETWORK (VNET)

September 25, 2016 09:45PM

Last article PART 2 : MICROSOFT AZURE CREATING RESOURCE GROUP I wrote on Resource Group. In this part, I will be deploying virtual network in same earlier created resource group. Before that I would like you to understand how virtual networks will look once I deploy it. New Virtual Network resource will be a part of Resource Group POC-VPN and the location is East US 2. I will be naming Virtual Network name vnet-poc-10.100.2.0. In this vNet I will be using address space 10.100.2.0/24, It provides me total 256 IP address. If require I can add more Address spaces to accommodate new VMs or other resource services in case I am running out of IPs, For my design I will not tend to use jumbo address pool for 16 bit subnet as shown in the Microsoft documents. I am going with smaller one 24 bit for per project (Resource Group) instead. Next I have got one address pool 10.100.2.0/24, I would like to break them into smaller IP subnets (IP Supernetting), In my scenario, I have created 3 Subnets. As shown In the table I can use Subnet01 for my database VMs and Subnet02 for application VMs, (I would like to associate Network security group (Firewall) between subnet, I will try it to cover in some other article). Third subnet GatewaySubnet is used by Microsoft Azure virutal network Gateway service for enabling cross-premises connectivity, You will have to create specially name the GatewaySubnet to get it used by Azure Gateway service, GatewaySubnet name is reserved and I will be creating it in Part 5 and Part 5.1. VMs should not assigned this network subnet (Mostly you won't be able to easily).

There might be a question what happened to IP range 10.100.2.128 to 10.100.2.223, I have not created it as I don't see any use right now, As my project goes on if i feel I running out of IPs I can create it later, Its kind of reserved by me for future use or designing.

Sr. IP subnet Name IP subnet Total Usable IP Usable IP range Network Subnet IP Broadcast IP Gateway IP
1 Subnet01 10.100.2.0/26 62 (3 IPs reserved by Azure) 10.100.2.1 to 10.100.2.62 0 63 10.100.2.1
2 Subnet02 10.100.2.64/26 62 (3 IPs reserved by Azure) 10.100.2.65 to 10.100.2.126 64 127 10.100.2.65
3 GatewaySubnet 10.100.2.224/27 When subnet created with name Gatewaysubnet complete block is reserved by Azure for gateway service.

Continuing from previous article, Click on Resource Groups >> Poc-VPN >> Overview click +Add.Microsoft Azure add new vnet resources in reources group poc vpn on Portal.azure.com

Once +Add button is press Azure portal will keep expanding new windows on the right hand side, Type and Search for Virtual Network, click it to create new virtual network and give it some name, Add the Address space, at first you can only create one subnet, once they vNet is created more subnets can be added later., Select correct subscription and Location. Resource group will be existing POC-VPN.

It might take some moment to create new VIrutal Network, Progress can be checked as shown in insight windows in below screenshot. Resource Groups can be refreshed to view created new resource object.Microsoft Azure create virtual network, subnets, address spaces, gateway

In the next series Part I will be deleting this vNet and repeating same steps with Azure Powershell

Hi Kunal,

The above information is very helpful for me. It will help me to reduce manual work.

Thanks in Advance for more useful information in future.

Thanks a lot for this post, please complete the entire network setup either Site to site or Point to site VPN

Thanks Kunal, (We both have same name :)) for your comments.

Thanks Shailender, for comments and working on the same to complete ASAP.
