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.

FaaS

Azure provides FaaS. These are serverless implementations from Azure. With Azure Functions, code can be written in any language the user is comfortable with and Azure Functions will provide a runtime to execute it. Based on the language chosen, an appropriate platform is provided for users to bring their own code. Functions are a unit of deployment and can automatically be scaled out and in. When dealing with functions, users cannot view the underlying virtual machines and platform, but Azure Functions provides a small window to view them via the Kudu Console.

There are two main components of Azure Functions:

  • The Azure Functions runtime
  • Azure Functions binding and triggers

Let's learn about these components in detail.

The Azure Functions runtime

The core of Azure Functions is its runtime. The precursor to Azure Functions was Azure WebJobs. The code for Azure WebJobs also forms the core for Azure Functions. There are...
