Azure for Architects - Third Edition

By: Ritesh Modi, Jack Lee, Rithin Skaria

Overview of this book

Thanks to its support for high availability, scalability, security, performance, and disaster recovery, Azure has been widely adopted to create and deploy different types of application with ease. Updated for the latest developments, this third edition of Azure for Architects helps you get to grips with the core concepts of designing serverless architecture, including containers, Kubernetes deployments, and big data solutions. You'll learn how to architect solutions such as serverless functions, you'll discover deployment patterns for containers and Kubernetes, and you'll explore large-scale big data processing using Spark and Databricks. As you advance, you'll implement DevOps using Azure DevOps, work with intelligent solutions using Azure Cognitive Services, and integrate security, high availability, and scalability into each solution. Finally, you'll delve into Azure security concepts such as OAuth, OpenConnect, and managed identities. By the end of this book, you'll have gained the confidence to design intelligent Azure solutions based on containers and serverless functions.

Architectural considerations for high availability

Azure provides high availability through various means and at various levels. High availability can be at the datacenter level, the region level, or even across Azure. In this section, we will go through some of the architectures for high availability.

High availability within Azure regions

The architecture shown in Figure 2.6 shows a high-availability deployment within a single Azure region. High availability is designed at the individual resource level. In this architecture, there are multiple VMs at each tier connected through either an application gateway or a load balancer, and they are each part of an availability set. Each tier is associated with an availability set. These VMs are placed on separate fault and update domains. While the web servers are connected to application gateways, the rest of the tiers, such as the application and database tiers, have internal load balancers...
