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.

Introduction to containers

Containers are referred to as operating system–level virtualization systems. They are hosted on an operating system running either on a physical server or a virtual server. The nature of the implementation depends on the host operating system. For example, Linux containers are inspired by cgroups; on the other hand, Windows containers are almost lightweight virtual machines with a small footprint.

Containers are truly cross-platform. Containerized applications can run on any platform, such as Linux, Windows, or Mac, uniformly without any changes being needed, which makes them highly portable. This makes them a perfect technology for organizations to adopt as they are platform-agnostic.

In addition, containers can run in any cloud environment or on-premises environment without changes being needed. This means that organizations are also not tied to a single cloud provider if they implement containers as their hosting platform on the cloud. They...
