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.

Azure high availability

Achieving high availability and meeting high SLA requirements is tough. Azure provides lots of features that enable high availability for applications, from the host and guest OS to applications using its PaaS. Architects can use these features to get high availability in their applications using configuration instead of building these features from scratch or depending on third-party tools.

In this section, we will look at the features and capabilities provided by Azure to make applications highly available. Before we get into the architectural and configuration details, it is important to understand concepts related to Azure's high availability.

Concepts

The fundamental concepts provided by Azure to attain high availability are as follows:

  • Availability sets
  • The fault domain
  • The update domain
  • Availability zones

As you know, it's very important that we design solutions to be highly available...
