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 API Management – API gateway

Azure API Management is a Platform-as-a-Service (PaaS) framework for publishing an organization's internal and external APIs. With Azure API Management, you can secure your internal or external APIs, or compose your own API that talks to your backend system to cater to the needs of client applications.

Like other serverless platforms, API Management also comes with a variety of pricing models. For example, you can run an instance of API Management with a consumption plan, or you can pay a fixed price to utilize services in both the standard and premium plans. You can integrate API Management as part of your ISE:

People are often confused by the role of API Management. API Management is not only the façade layer preceding your APIs, but also a security door to your enterprise data. A better solution design should also cater to the security aspect of talking to internal or external services.

We have seen stories where organizations continue creating a plethora of APIs to connect their internal or external business partners, without paying much attention to security, content-type handling, caching, and so on. Often, these service behaviors are managed on an individual basis, which is not suited to a highly scalable infrastructure.

In Chapter 4, Azure API Management, we will discuss these aspects in more detail, along with industry best practices, so that you can get the most out of your investment and make your organization more agile and secure.
