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.

Exploring Azure message queues

Microsoft Azure Service Bus is a fully managed enterprise integration message broker. Some common messaging scenarios are included in Service Bus, such as messaging in case of transferring data or decoupling applications to improve their reliability and their scalability and message sessions by implementing workflows that require message ordering, for example, or topics and subscriptions.

Azure supports the following two types of queuing mechanisms:

  • Queue Storage is a simple message queue service for storing large numbers of messages
  • Service Bus queues are part of a broader set of messaging services that support queuing, publishing/subscribing, and advanced integration patterns

Azure Queue Storage is a service for sending and receiving messages but is also used to store a large number of messages; a queue message can be up to 64 KB in size.
