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.

Uploading employee data to blob storage

In this recipe, we'll develop a console application for uploading the CSV sheet to blob storage.

Getting ready

Perform the following steps:

  1. Install Visual Studio 2019.
  2. Create a storage account and create a blob container with the name csvimports.
  3. Create a CSV file with some employee data, as shown in Figure 8.2:
    Creating a CSV file with multiple employees’ data
Figure 8.2: CSV file with employee data

How to do it...

In this section, we are going to create a .NET Core–based client application that uploads the csv file to the blob container by performing the following steps:

  1. Create a new Console App (.NET Core) project named CSVImport.Client using Visual Studio, as shown in Figure 8.3:

  2. Once the project is created, execute the following commands in the NuGet package manager:
    Install-Package Microsoft.Azure.Storage.blob 
    Install-Package Microsoft.Extensions.Configuration...
