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.

Logic Apps control flow actions

To work effectively with a Logic Apps workflow, it is important to understand the utility of control flow actions. In this section, we will discuss the following pre-built control flow actions available in Azure Logic Apps and Microsoft Flow:

  • Conditional actions
  • Parallel actions
  • Switch actions
  • Foreach actions
  • Scope actions
  • Do…Until actions
  • Terminate actions

We will describe how you can use these control flow actions against a set of triggers to build event-based cloud solutions in Azure. We will also discuss various data operation actions, such as Compose, Parse JSON, join, Filter array, and select.

Conditional actions

Conditional actions in Logic Apps provide if…else constructs...
