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.

The components of Azure Logic Apps

With great IDE support, development with Logic Apps is very easy. In this section, we will describe the various components of Logic Apps and their purposes.

Azure Logic Apps uses a workflow definition template to create Logic Apps workflows in JSON format. The workflow definition template schema consists of multiple sections, such as parameters, triggers, actions, and outputs. When we create a workflow within Azure Logic Apps, the Logic Apps workflow engine validates the workflow definition through this predefined schema structure.

The basic structure of a workflow definition schema is as follows:

Here, we will go through each of the sections described in the workflow definition schema. This will help us to understand how the Azure Logic Apps engine and the workflow schema validation work behind the integration framework:
