Join David Elfassy for an in-depth discussion in this video Creating virtual networks, part of Microsoft Azure: Networking Concepts.
- [Instructor] So we need to build out our networking infrastructure as part of our Azure subscription because our plan is to store our resources, our servers, and to make them accessible to the world, both on premises and public resources that would be accessible from anywhere on the internet. So the first step that I need to do is actually create the networking environment for those resources. And that networking environment will start off with a virtual network. Now I showed you in an earlier video that I can go down in my list of resources here, click on More services and find the virtual network.
Or I can click here on New, go down to Networking, and click on Virtual network. So, I'm going to create the virtual network. Now this interface that is open now is called a blade and there are several blades that we'll open side by side. You'll note that the first question that I'm asked is what will be my deployment model. Now I have two deployment model option: Resource Manager as we've discussed in earlier videos in this course, or Classic. Resource Manager again will give me the opportunity to perform multiple tasks with multiple objects that are managed as part of a single entity.
Those include being redeployed and monitored and many other tasks that we can perform on those various objects. So I'm going to create a resource that will be within the Resource Manager deployment model. Now the next blade provides me some more specific questions and information about this virtual network. And the first thing I'm going to need to do is give it a name. So we're going to give this network a name. It will be my first network in my environment so I will call it LinkedIn-Vnetwork-1.
The next list of configuration here is for the Address space. The Address space is denoted in a CRDR annotation. This forward slash 16 CRDR annotation defines the number of bits that are being used to define the addressing solution here. This here from 10.0.0.0 to 10.0.255.255 defines that I've got roughly 65 thousand IP addresses available to me within this range. Please note that the address range here once it is specified at the creation of the virtual network it cannot be modified later on.
So you need to be sure that you've got a large enough address range. Don't worry, you'll be able to segment within that address range because we've got Subnets within our address range as well. So what I'm going to do here is I have one Subnet that provides 256 addresses within this range. So you'll want to have a larger range and then a smaller Subnet range. So I can modify those as well if I want to but these will be good enough for my demonstration. Next I've got the details of my Subscription.
Now my Subscription is essentially how I'm paying for all of these resources and I've got a Pay-As-You-Go subscription, which means that I get a bill at the end of the month, then it gets charged to my credit card. And then I've got my Resource group. Now the Resource group is part of that resource management solution that I mentioned earlier and all of those resources that will be managed as a single entity. Now I don't have a Resource group yet. So I'm going to create a new one. So I'm going to call it LinkedIn-ResourceGroup.
And I don't actually need to number it because I'm only going to be creating one and then I will be putting all of my resources within this group. Next is my Location. Now the Location is the actual data center where this resource will be located. Microsoft has data centers all over the world and especially here I see many of them in North America. It defaults to Canada East because that is where my subscription was created and my account actually was created in Canada and it notices that my account is in Canada. Even though when I'm creating this resource I'm not physically in Canada right now, it actually defaults to Canada East which is my home location.
So you can pick any location here. I'm going to keep Canada East because that will work just fine. And then I'm going to click on Create. Notice that a validation happens and all these green checkboxes are being checked as my virtual network is being created. The deployment of the virtual network has started and we can go see it's status by clicking on All resources. And to go look at the resource, now the resource has not yet been created. The resource is still under deployment as you see here, the deployment is going on.
And with the magic of video editing we will return when the resource has been created. And now I have a new message Deployment to resource group LinkedIn was successful. I'm going to refresh my interface here of my dashboard. And now I see my virtual network has been created.
