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 and Logic Apps

Before we dive into various integration patterns, let's discuss the difference between Logic Apps and Azure Functions. As we know, Logic Apps and Azure Functions are both part of the serverless family and both have a robust platform engine running behind the scenes. It's very important for us to know the difference between the two, as this will enable us to pick the right option for our compute operations.

Development experience: Azure Functions follow an event-based programming model and works with a code-first approach, whereas Logic Apps are workflows triggered through events and messages.

From a development point of view, the developer can choose a language of their choice, such as C#, F#, JavaScript, Node.js, or PowerShell, to develop event-based executable code with support for multiple integrated development environments, including...
