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.

Developing Event-Based and Message-Based Solutions

In this chapter, we will explore the use of event-based and message-based solutions. We will publish and subscribe from a web application, see how we can send and receive messages from a Service Bus queue by using the same application, discover the operating mode of Event Grid and how it connects to services and event handlers, and explore Azure Event Hubs.

In this chapter, we’re going to cover the following main topics:

  • Exploring Event Grid and Azure Event Hubs
  • Exercise 1 – publishing and subscribing from a .NET app to Event Grid events
  • Exploring Azure message queues
  • Exercise 2 – creating an Azure Service Bus namespace and a queue
  • Exercise 3 – publishing messages to a Service Bus queue using a .NET Core application
  • Exercise 4 – reading messages from a Service Bus queue using a .NET Core application
  • Exercise 5 – sending and receiving messages to and from a...
