Overview of this book

Over the years, Azure cloud services have grown quickly, and the number of organizations adopting Azure for their cloud services is also gradually increasing. Leading industry giants are finding that Azure fulfills their extensive cloud requirements. Azure for Architects – Second Edition starts with an extensive introduction to major designing and architectural aspects available with Azure. These design patterns focus on different aspects of the cloud, such as high availability, security, and scalability. Gradually, we move on to other aspects, such as ARM template modular design and deployments. This is the age of microservices and serverless is the preferred implementation mechanism for them. This book covers the entire serverless stack available in Azure including Azure Event Grid, Azure Functions, and Azure Logic Apps. New and advance features like durable functions are discussed at length. A complete integration solution using these serverless technologies is also part of the book. A complete chapter discusses all possible options related to containers in Azure including Azure Kubernetes services, Azure Container Instances and Registry, and Web App for Containers. Data management and integration is an integral part of this book that discusses options for implementing OLTP solutions using Azure SQL, Big Data solutions using Azure Data factory and Data Lake Storage, eventing solutions using stream analytics, and Event Hubs. This book will provide insights into Azure governance features such as tagging, RBAC, cost management, and policies. By the end of this book, you will be able to develop a full-?edged Azure cloud solution that is Enterprise class and future-ready.

ARM Templates - Modular Design and Implementation

We know that there are multiple ways to author an ARM template. It is quite easy to author one that provisions all of the needed resources in Azure using Visual Studio and Visual Studio Code. A single ARM template can consist of all the required resources for a solution on Azure. This single ARM template could be as small as a few resources, or it could be a larger one consisting of many resources.

While authoring a single template consisting of all resources is quite tempting, it is advisable to plan an ARM template implementation divided into multiple smaller ARM templates beforehand so that future troubles related to them can be avoided.

In this chapter, we will look at how to write ARM templates in a modular way so that they can evolve over a period of time with minimal involvement in terms of changes and effort in testing...
