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.

Using outputs between ARM templates

One of the important aspects that can easily be overlooked while using linked templates is that there might be resource dependencies within linked templates. For example, a SQL Server resource might be in a linked template that is different to that of a virtual machine resource. If we want to open the SQL Server firewall for the virtual machine IP address, then we should be able to dynamically pass this information to the SQL Server firewall resource after provisioning the virtual machine.

This could be done using the simple method of referring to the IP address resource using the REFERENCES function if the SQL Server and virtual machine resources are in the same template.

It becomes slightly more complex in the case of linked templates if we want to share runtime property values from one resource to another when they are in different templates.

ARM templates provide an outputs configuration, which is responsible for generating outputs from...
