Overview of this book

Microsoft provides a solution for easily running small segments of code in the cloud with Azure Functions. The second edition of Azure Serverless Computing Cookbook starts with intermediate-level recipes on serverless computing along with some use cases demonstrating the benefits and key features of Azure Functions. You’ll explore the core aspects of Azure Functions, such as the services it provides, how you can develop and write Azure Functions, and how to monitor and troubleshoot them. As you make your way through the chapters, you’ll get practical recipes on integrating DevOps with Azure Functions, and providing continuous integration and continuous deployment with Azure DevOps. This book also provides hands-on, step-by-step tutorials based on real-world serverless use cases to guide you through configuring and setting up your serverless environments with ease. You will also learn how to build solutions for complex, real-world, workflow-based scenarios quickly and with minimal code using Durable Functions.

Reading Excel data using activity functions

In this recipe, we will retrieve all data from specific Excel sheets by writing an activity function.

Let's now make some code changes to the Orchestration function by writing a new activity function that can read data from an Excel sheet that has been uploaded to the blob container.

Getting ready

In this recipe, we will create an activity trigger named ReadExcel_AT that reads data from the blob that's stored in the storage account. This activity trigger performs the following jobs:

  1. Connects to the blob using a function, ReadBlob, of a class named StorageManager.
  2. Reads the data from the Excel sheet using a component called EPPlus. You can read more about it at https:...
