Azure Serverless Computing Cookbook - Third Edition

By: Praveen Kumar Sreeram

Overview of this book

This third edition of Azure Serverless Computing Cookbook guides you through the development of a basic back-end web API that performs simple operations, helping you understand how to persist data in Azure Storage services. You'll cover the integration of Azure Functions with other cloud services, such as notifications (SendGrid and Twilio), Cognitive Services (computer vision), and Logic Apps, to build simple workflow-based applications. With the help of this book, you'll be able to leverage Visual Studio tools to develop, build, test, and deploy Azure functions quickly. It also covers a variety of tools and methods for testing the functionality of Azure functions locally in the developer's workstation and in the cloud environment. Once you're familiar with the core features, you'll explore advanced concepts such as durable functions, starting with a "hello world" example, and learn about the scalable bulk upload use case, which uses durable function patterns, function chaining, and fan-out/fan-in. By the end of this Azure book, you'll have gained the knowledge and practical experience needed to be able to create and deploy Azure applications on serverless architectures efficiently.

Business problem

In general, every organization uses applications that are hosted on multiple platforms across different datacenters (either on the cloud or on-premises). Often, there will be a need to feed data from one application to another system. Usually, CSV spreadsheets (or, in some cases, JSON or XML files) are used to export data from one application and import it into another application.

You may think that exporting CSV files from one application to another would be a straightforward job, but if there are many applications that need to feed data to other applications, and on a weekly/monthly basis, then this process would become very tedious and there is a lot of scope for manual error. So, the solution is obviously to automate the process as far as possible.

In this chapter, we'll learn how to develop a durable solution based on serverless architecture using Durable Functions. Chapter 7, Developing reliable serverless applications using durable functions, already...
