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.

SQL database pricing

Azure SQL previously had just one pricing model—a model based on DTUs—but an alternative pricing model based on vCPUs has also been launched. The pricing model is selected based on the customer's requirements. The DTU-based model is selected when the customer wants simple and preconfigured resource options. On the other hand, the vCore-based model offers the flexibility to choose compute and storage resources. It also provides control and transparency.

Let's take a closer look at each of these models.

DTU-based pricing

The DTU is the smallest unit of performance measure for Azure SQL Database. Each DTU corresponds to a certain amount of resources. These resources include storage, CPU cycles, IOPS, and network bandwidth. For example, a single DTU might provide three IOPS, a few CPU cycles, and IO latencies of 5 ms for read operations and 10 ms for write operations.
