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.

Outputs in the Logic Apps workflow template

Outputs define the data that the Logic Apps workflow can return when finishing execution. This might include status or field tracking within a Logic Apps workflow with each run.

Output variables are key-value pairs and, once configured, you can track the values through a logic app's run history in the Azure portal, or you can pass the key-value pair to external systems such as Power BI to view on the dashboard:

The following table contains parameters for outputs in a Logic Apps workflow:

Element Required Type Description

Key-name

Yes string The key name for the output return value

Type

Yes int, float, string, SecureString, bool, array, JSON object The default value of the parameter

Values

No Same as type The return value

We have now covered most of the theory, so it's time to work through some exercises...
