Network Gateways in Azure

Hi Friends,

In the previous section, we have seen how to setup peering. But this comes with a cost. Before discussing network gateways in azure, let’s understand the costing part of peering.

  • One thing to note here, although virtual networks upto 50 is free but peering comes with a cost.
  • Below, I have explained the costing for the same.

Configure VNet Peering

Hi Friends,

In this section, we will see how to configure peering between virtual networks.

  • Right now, we have two virtual network that are setup to talk to each other over peering relationship.
  • But, in previous example, we have actually setup global peering itself means virtual network setup in one region is talking to another region.
  • Same peering relationship can be setup for the same region itself. Currently, we have three virtual networks as shown below.

Connecting between virtual networks in azure

Hi Friends,

In this section, we are going to discuss how to connect between virtual networks.

  • Its important to understand that how Azure implements security across virtual networks. By default, a machine which is one virtual network cannot communicate with a machine or any other resource on the other virtual network.
  • Any storage resource can be communicated via public end points and associated keys. But, if you have associated your storage account to a private end point, on a virtual network, then you will find that virtual machine on another network cannot communicate with it.
  • But, that doesn’t stop networking. We can actually setup peering relationship between the two networks.

Application security groups in Azure

Hi Friends,

In this section, we will continue from the last blog and discuss more about application security groups.

  • Application security groups are the enhancements of network security groups. It allows you to reduce the number of network security groups (NSGs) you require or the number of security rules that you require.

  • The way it does that by grouping resources based on the same rules. So, instead of creating network security groups for the every subnet which you have and then separate rules for each resource; you can put all of your SQL Server dbs, all of your app servers, web servers into the same security group.
  • Let’s create a one. Search for application security groups in all services.

Route Tables in Azure

Hi Friends,

In this section, we will continue from the last section and see how to get started with route table.

  • Next, we are going to create a route table. A route table is basically a list of IP address ranges. And, this will tell Microsoft azure how to send traffic which is coming over your network. Hence, let’s search for the same in all services.

Manage Virtual Networks


In this section, we are going to discuss below things about virtual networks.

  • Virtual networking is the backbone which allows resources to talk to each other in different regions or in the same region.
  • There are various techniques Microsoft is offering to allow us to do that.
  • Let’s start by creating a virtual network. We can search in all services
