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

Securing the communication channels


Your Service Fabric application is deployed on the Service Fabric cluster, which is a set of federated nodes that talk to each other over the network.

The generic structure of your Service Fabric cluster looks like the following:

Generic structure of Service Fabric cluster

As you can see, there are two types of communication channels that are used by the Service Fabric:

  • Channel to enable communication between cluster nodes (node-node)
  • Channel to enable communication between clients and nodes (client-node)

Although you can choose not to secure the communication channels, by using open channels anonymous users can connect to the cluster and perform management operations on it and alter the cluster. Security cannot be an afterthought of implementation as an unsecured Service Fabric cluster cannot be secured later. Therefore, you should consider security of your cluster prudently.

Inter-node communication

Inter-node security ensures that only the authorized nodes...
