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.

Understanding Azure VNet architecture


Understanding a concept and learning how to do a specific task is very fulfilling for most people who are seeking to learn something. However, this section will take you beyond that and will introduce what is going on behind the scenes, what Microsoft uses to get its Azure networking to work properly, and so on.

Microsoft Azure mainly takes advantage of Software-Defined Networking (SDN) for the internal operations of Azure, but this is not the case for the case when the customers work with Azure as they are communicating with Azure via the internet most of the time, which is called the edge. In this part of the network, Microsoft uses physical networking.

Put simply, the concept of using virtual networks with subnets and virtual network gateways is running on the backbone of Azure. However, on the edge physical network devices, such as routers, switches, firewalls, and so on, are used.

Throughout the book, all of the SDN services, such as Azure Load Balancers...
