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

Service Fabric discovery and communication


An application built on top of Microservices is usually composed of multiple services, each of which runs multiple replicas. Each service is specialized in a specific task. To achieve an end-to-end business use case, multiple services will need to be stitched together. This requires services to communicate to each other. A simple example would be a web frontend service communicating with the middle-tier services, which in turn connects to the backend services to handle a single user request. Some of these middle-tier services can also be invoked by external applications.

Services deployed on Service Fabric are distributed across multiple nodes in a cluster of virtual machines. The services can move across dynamically. This distribution of services can either be triggered by a manual action or be result of Service Fabric cluster manager rebalancing services to achieve optimal resource utilization. This makes communication a challenge as services are...
