Hands-On Networking with Azure

By: Mohamed Waly

Overview of this book

Microsoft Azure networking is one of the most valuable and important offerings in Azure. No matter what solution you are building for the cloud, you'll fi nd a compelling use for it. This book will get you up to speed quickly on Microsoft Azure Networking by teaching you how to use different networking services. By reading this book, you will develop a strong networking foundation for Azure virtual machines and for expanding your on-premise environment to Azure. Hands-On Networking with Azure starts with an introduction to Microsoft Azure networking and creating Azure Virtual Networks with subnets of different types within them. The book helps you understand the architecture of Azure networks. You will then learn the best practices for designing both Windows- and Linux-based Azure VM networks. You will also learn to expand your networks into Azure and how to use Azure DNS. Moreover, you will master best practices for dealing with Azure Load Balancer and the solutions they offer in different scenarios. Finally, we will demonstrate how the Azure Application Gateway works, offering various layer-7 load balancing capabilities for applications. By the end of this book, you will be able to architect your networking solutions for Azure.

VNet2VNet connection


As discussed in Chapter 2, Delving into Azure Virtual Networks, you can create a peer between two virtual networks within the same region to let the services within these two virtual networks communicate with each other seamlessly. At the time of writing you can peer two virtual networks within different regions, but this feature is still in preview, and not supported in all regions, and not even as highly available and reliable as the traditional peering. Therefore, we only have one way to do such a connection now: using VNet2VNet.

Creating a VNet2VNet connection is not similar to the model of VNet peering, because it uses a Site-to-Site IP Sec connection, which is similar to VPN communication with on-premises. Virtual network peering uses the Microsoft backbone network to communicate. As a result, when you want to deploy a VNet2VNet connection, you will need a VPN gateway to provide secure tunneling.
