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.

Integrating Azure Key Vault to configure application secrets

One of the major parts of any project is handling secrets in an efficient manner to adhere to organization-wide security guidelines. It's not advised to maintain secrets (such as passwords) in code or in files that are accessible to developers or any other stakeholders. In fact, these days, all the production environment details are only accessible by a few people and the secrets are managed by various systems. One such system in Azure is Key Vault. In this recipe, we'll learn how to leverage Key Vault to manage a secret that can be accessed by the code in a function app.

How to do it…

In this recipe, we will work on the following steps:

  1. Creating a secret in the Key Vault service.
  2. Configuring the Azure DevOps release pipeline.
  3. Configuring the access policy.
