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.

High availability

High availability forms one of the core non-functional technical requirements for any business-critical service and its deployment. High availability refers to the feature of a service or application that keeps it operational on a continuous basis; it does so by meeting or surpassing its promised service level agreement (SLA). Users are promised a certain SLA based on the service type. The service should be available for consumption based on its SLA. For example, an SLA can define 99% availability for an application for the entire year. This means that it should be available for consumption by users for 361.35 days. If it fails to remain available for this period, that constitutes a breach of the SLA. Most mission-critical applications define their high-availability SLA as 99.999% for a year. This means the application should be up, running, and available throughout the year, but it can only be down and unavailable for 5.2 hours...
