A Developer's Guide to Building Resilient Cloud Applications with Azure

By: Hamida Rebai Trabelsi

Overview of this book

To deliver software at a faster rate and reduced costs, companies with stable legacy systems and growing data volumes are trying to modernize their applications and accelerate innovation, but this is no easy matter. A Developer’s Guide to Building Resilient Cloud Applications with Azure helps you overcome these application modernization challenges to build secure and reliable cloud-based applications on Azure and connect them to databases with the help of easy-to-follow examples. The book begins with a basic definition of serverless and event-driven architecture and Database-as-a-Service, before moving on to an exploration of the different services in Azure, namely Azure API Management using the gateway pattern, event-driven architecture, Event Grid, Azure Event Hubs, Azure message queues, FaaS using Azure Functions, and the database-oriented cloud. Throughout the chapters, you’ll learn about creating, importing, and managing APIs and Service Fabric in Azure, and discover how to ensure continuous integration and deployment in Azure to fully automate the software delivery process, that is, the build and release process. By the end of this book, you’ll be able to build and deploy cloud-oriented applications using APIs, serverless, Service Fabric, Azure Functions, and Event Grid technologies.

Creating and Deploying a Function App in Azure

One of the critical decisions architects and developers make in the phase of architecting a new cloud software or application is how to connect to the backend services, run background processing, run backend tasks, and carry out more tasks, such as scheduling and sending emails, without affecting the main application processing. For this, the Azure Functions app can be useful.

We can use Azure Functions to execute code in a cloud environment in a serverless way. All we need to do is to write less code with a low cost for a specific problem without caring about the whole application, even the infrastructure where we will run it. We will focus, in this case, on logic and business scope. We can execute Azure Functions in response to events as well.

In this chapter, we will cover the basic concepts of Azure Functions and the hosting plan options. We will explore the development of Azure functions and develop durable functions, which...
