Overview of this book

This Learning Path helps you understand microservices architecture and leverage various services of Microsoft Azure Service Fabric to build, deploy, and maintain highly scalable enterprise-grade applications. You will learn to select an appropriate Azure backend structure for your solutions and work with its toolkit and managed apps to share your solutions with its service catalog. As you progress through the Learning Path, you will study Azure Cloud Services, Azure-managed Kubernetes, and Azure Container Services deployment techniques. To apply all that you’ve understood, you will build an end-to-end Azure system in scalable, decoupled tiers for an industrial bakery with three business domains. Toward the end of this Learning Path, you will build another scalable architecture using Azure Service Bus topics to send orders between decoupled business domains with scalable worker roles processing these orders. By the end of this Learning Path, you will be comfortable in using development, deployment, and maintenance processes to build robust cloud solutions on Azure. This Learning Path includes content from the following Packt products: • Learn Microsoft Azure by Mohamed Wali • Implementing Azure Solutions - Second Edition by Florian Klaffenbach, Oliver Michalski, Markus Klein • Microservices with Azure by Namit Tanasseri and Rahul Rai

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,...
