Azure Architecture Best Practice for securing Azure Virtual Networks
While designing the azure landing zone we need to ensure that our network is secured.VNet protects inbound flow (from users) and outbound traffic flow (to the Internet). Now the question arises how do we secure this traffic? Azure provides services like Azure firewall and Azure Application Gateway. It is very confusing when to use Azure firewall vs. Azure Application Gateway. There can be other combinations that can make the design more and more complex. This article provides the definitive guide and scenarios-based approach to help what design should be used. When it should be used? How it should be used?
Troubleshooting user defined routes in Azure
In this blog, we will discuss how to troubleshoot the user-defined route in Azure. I have faced this issue in one of my projects. Typically when you want to test the traffic from a specific VM you will have to log in to the VM and see the output of the Traceroute command and it becomes cumbersome if you have so many routes because now you have to log in to each VM to verify whether the routes are working correctly or not. Another problem is that even if the routes are not working traceroute will not show why it is not working. So if you do not know why routes are not working you can not fix anything. To overcome this issue I wrote a small script that can be used as it is by changing the parameters and it will display the connectivity status (success or failure) if there is an issue then this script will also show what is causing that issue.
