Microsoft Azure networking is one of the most valuable and important offerings in Azure. It's impossible to imagine an environment without networks. No matter what solution you are building for the cloud, you'll find a compelling use for Azure networking. This book will get you up-to-speed on Microsoft Azure networking by teaching you how to use the different networking services. Based on real-world scenarios, you will be able to leverage secure design patterns. By reading this book, you will develop a strong networking foundation for Azure Virtual Machines, and for expanding your on-premise environment to Azure.
This book starts with an introduction to Microsoft Azure Networking and how to create Azure Virtual Networks with subnets of different types within them. This book will also help you understand the architecture of Azure networks and how it integrates with other Azure services. You will then learn the best practices for designing your Azure VM networks, whether Windows or Linux-based. You will also learn how to expand your networks into Azure, and how to use Azure DNS. Moreover, you will master best practices to deal with Azure Load Balancers (followed by the role of Azure Traffic Manager) and the solutions they offer in different scenarios. Finally, this book demonstrates the workings of Azure Application Gateway, which offers various layer-7 load balancing capabilities for applications.
This book targets developers, IT professionals, and even database admins who have experience of working with Microsoft Azure and want to make the most of Azure networking services. It would also be a great guide for network engineers who would like to learn Azure.
Chapter 1, Azure Virtual Networks 101, introduces Azure and its models in addition to Azure Virtual Networks and subnets, and how to create and manage them. By the end of the chapter, you will have learned how to automate manual tasks implemented throughout the chapter using Azure PowerShell and Azure CLI 2.0.
Chapter 2, Delving into Azure Virtual Networks, introduces Azure networking architecture and what is going on behind the scenes. Also, you will learn how to work with Virtual Networks service endpoints and network security groups. By the end of the chapter, you will have learned how to automate manual tasks.
Chapter 3, Azure Network for VMs, introduces Azure VMs and how to design and implement networking solutions for Azure VMs. By the end of the chapter, you will have learned how to automate manual tasks.
Chapter 4, Network Connectivity Scenarios in Azure, introduces the most common scenarios for extending your on-premises to Azure, which includes how to implement those scenarios.
Chapter 5, Azure DNS, introduces how to use Azure DNS as a service, managing your zones on Azure, delegating zones, and even working with reverse DNS zones in Azure. By the end of the chapter, you will have learned how to automate manual tasks.
Chapter 6, Azure Load Balancers, introduces Azure Load Balancer and its importance, followed by a step-by-step guide on how to configure Azure Load Balancer.
Chapter 7, Azure Traffic Manager, introduces Azure Traffic Manager and its importance, followed by a step-by-step guide on how to configure Azure Traffic Manager. By the end of the chapter, you will have learned how to automate manual tasks.
Chapter 8, Azure Application Gateway, introduces Azure Application Gateway and its importance, followed by a step-by-step guide on how to configure Azure Application Gateway.
It's highly recommended to have knowledge of virtualization and networking, such as Hyper-V/VMware/Citrix, or CCNA .
Having knowledge of other Azure services will be a great benefit. You can check out my other book about Azure Storage at the following link: https://www.packtpub.com/big-data-and-business-intelligence/learning-microsoft-azure-storage.
