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

Stateful service


A stateful Microservice stores state information stored in a consistent and highly available manner using reliable data structure. By default, the state data is saved on the disk of the compute node. However, you can write your own state providers to store state data externally and consume it. Service Fabric ensures that your state data is consistent and highly available so that, in case of failure of primary compute node, a secondary node can resume processing without loss of data.

Stateful service architecture

A stateful service takes requests from clients through the ICommunicationListener interface:

Stateful Reliable Service architecture

The implementation of a stateful reliable service derives from StatefulService class. Service Fabric runtime manages the lifetime of your stateful Microservice through the StatefulService class. The service can use Reliable Collections to persist state information, which are similar to collections in System.Collections namespace but with...
