What this book covers
Chapter 1, Azure Networking Fundamentals, introduces core concepts of Azure networking, such as virtual networks, public and private IP addressing, network segmentation using subnets, and routing concepts.
Chapter 2, Design and Implement Name Resolution, covers the four DNS implementation options for virtual networks in Azure and their use cases: Azure-provided name resolution, customer-managed DNS servers, Azure DNS private zones, and Azure DNS public zones.
Chapter 3, Design, Implement, and Manage VNet Routing, explains Azure routing, and you will create custom routes to control traffic flow. You will learn how to redirect traffic through network virtual appliances so you can inspect the traffic before it’s allowed through. You will also learn how to implement Azure Route Server – a fully managed service that simplifies dynamic routing between your network virtual appliance (NVA) and Azure Virtual Network.
Chapter 4, Design and Implement Cross-VNet Connectivity, covers the design and implementation of cross-VNet connectivity using VNet peering.
Chapter 5, Design and Implement Hybrid Network Connectivity with VPN Gateway, covers one of the diverse options to connect remote users and networks to networks in Azure offered by the Azure cloud – the Azure VPN Gateway service, which allows us to create a secure connection between remote networks and Azure VNets over the public internet.
Chapter 6, Design and Implement Hybrid Network Connectivity with an ExpressRoute Gateway, explores the implementation of ExpressRoute, another gateway service offered by Azure, as an alternative solution for remote network connectivity. ExpressRoute connections bypass the public internet, which means that traffic takes fewer hops and has fewer points of failure that could cause network disruption.
Chapter 7, Design and Implement an Azure Virtual WAN Architecture, explains how to design a scalable network architecture in Azure using the VWAN service.
Chapter 8, Design and Implement Network Security, looks into securing the Azure network perimeter and VNet workloads using native capabilities such as DDoS protection, Azure Firewall, and Azure Firewall Manager.
Chapter 9, Design and Implement Application Delivery Services, discusses the four main load balancing services in Azure (Load Balancer, Application Gateway, Front Door, and Traffic Manager) and aspects to consider when designing and implementing these services.
Chapter 10, Design and Implement Platform Service Connectivity, looks at the three main options to control network connections to services when deploying platform services outside of customer-managed virtual networks in Azure (a platform service firewall, a service endpoint, and a private endpoint). This chapter will provide you with a clear understanding of these three options and how to design and implement them.
Chapter 11, Monitoring Networks in Azure, covers network monitoring and diagnostics – essential components in maintaining the smooth functioning and optimal performance of a network infrastructure. In this chapter, we will cover the tools available in Azure Network Watcher that we can use to monitor and diagnose network services.
