Serverless Integration Design Patterns with Azure

By: Abhishek Kumar, Srinivasa Mahendrakar

Overview of this book

With more enterprises adapting cloud-based and API-based solutions, application integration has become more relevant and significant than ever before. Parallelly, Serverless Integration has gained popularity, as it helps agile organizations to build integration solutions quickly without having to worry about infrastructure costs. With Microsoft Azure’s serverless offerings, such as Logic Apps, Azure Functions, API Management, Azure Event Grid and Service Bus, organizations can build powerful, secure, and scalable integration solutions with ease. The primary objective of this book is to help you to understand various serverless offerings included within Azure Integration Services, taking you through the basics and industry practices and patterns. This book starts by explaining the concepts of services such as Azure Functions, Logic Apps, and Service Bus with hands-on examples and use cases. After getting to grips with the basics, you will be introduced to API Management and building B2B solutions using Logic Apps Enterprise Integration Pack. This book will help readers to understand building hybrid integration solutions and touches upon Microsoft Cognitive Services and leveraging them in modern integration solutions. Industry practices and patterns are brought to light at appropriate opportunities while explaining various concepts.

Azure Functions hosting architecture

In the Azure portal, we need to create a function app for creating Azure Functions. A function app provides the execution context for individual functions. All configuration done at the function-app level will be applied to all Azure Functions. The following is an example of an Azure Function app named ShipAnyWhere-AzureFunction and a function called UpdateInventory:

These function apps are run and maintained by the Azure App Service platform, which is an Azure service used for hosting web applications, REST APIs, and mobile backends. The following is a layer diagram showing the dependencies of an Azure Functions runtime over other Azure technologies:

From the preceding diagram, it is clear that the root of Azure Functions is the Azure App Service platform, which brings following core capabilities to Azure Functions:

  • It provides the ability...
