Microservices with Azure

Overview of this book

Microsoft Azure is rapidly evolving and is widely used as a platform on which you can build Microservices that can be deployed on-premise and on-cloud heterogeneous environments through Microsoft Azure Service Fabric. This book will help you understand the concepts of Microservice application architecture and build highly maintainable and scalable enterprise-grade applications using the various services in Microsoft Azure Service Fabric. We will begin by understanding the intricacies of the Microservices architecture and its advantages over the monolithic architecture and Service Oriented Architecture (SOA) principles. We will present various scenarios where Microservices should be used and walk you through the architectures of Microservice-based applications. Next, you will take an in-depth look at Microsoft Azure Service Fabric, which is the best–in-class platform for building Microservices. You will explore how to develop and deploy sample applications on Microsoft Azure Service Fabric to gain a thorough understanding of it. Building Microservice-based application is complicated. Therefore, we will take you through several design patterns that solve the various challenges associated with realizing the Microservices architecture in enterprise applications. Each pattern will be clearly illustrated with examples that you can keep referring to when designing applications. Finally, you will be introduced to advanced topics such as Serverless computing and DevOps using Service Fabric, to help you undertake your next venture with confidence.

Webhook and API function apps


The webhook and API functions get triggered by events in external services such as GitHub, TFS, Office 365, OneDrive, and Microsoft PowerApps.

With the webhook and API functions, you can build notification Nanoservices that can perform custom operations whenever they receive a message on a configured webhook. For example, you can use webhooks with OneDrive that notifies your Nanoservice whenever a file gets uploaded to a folder.

Webhook and API functions accept a request and return a response. They mimic the web API or web service flows. These functions generally require some CORS (Cross-Origin Resource Sharing) settings to be managed. While developing the Nanoservices you can use an asterisk wildcard so they are wide open. However, you need to be aware that to invoke these Nanoservices from other services, you would need to set the cross-origin information in your function app settings.

These types of functions are generally used for exposing functionality to...
