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.

Single Instance

Single Instance databases are hosted as a single database on a single logical server. These databases do not have access to the complete features provided by SQL Server. Each database is isolated and portable. Single instances support the vCPU-based and DTU-based purchasing models that we discussed earlier.

Another added advantage of a single database is cost-efficiency. If you are in a vCore-based model, you can opt for lower compute and storage resources to optimize costs. If you need more compute or storage power, you can always scale up. Dynamic scalability is a prominent feature of single instances that helps to scale resources dynamically based on business requirements. Single instances allow existing SQL Server customers to lift and shift their on-premises applications to the cloud.

Other features include availability, monitoring, and security.

When we started our section on Azure SQL Database, we mentioned elastic pools as well. You can also...
