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.

Building Nanoservices with Azure Functions


Azure Functions allow developers to write serverless applications, meaning that developers or operations do not have to worry about the infrastructure on which the application executes. In many scenarios, application or business needs require a small piece of logic to be reused by other services for some small task to be performed based on an event such as sending a notification to user when a message is sent to a queue.

Such tasks were previously handled by WebJobs or scripts, which are difficult to reuse and connect in a flow of logic. Azure Functions give developers the ability to wrap the logic in a Nanoservice that can connect and communicate with other services to carry out the logic flow.

Azure Functions is part of web and mobile suite of services in Azure. In addition to Visual Studio tooling, you can design and manage Azure Functions from a dedicated portal at: https://functions.azure.com.

Currently you can create functions in JavaScript,...
