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

Health evaluation


Health evaluation can be performed manually by a user or by automated services employed to report on the system health. Health policies are used to evaluate and report the health of an entity which is then aggregated at a parent level in the entity hierarchy. This process cascades up to the root element of the hierarchy which is the Cluster. The following diagram illustrates this process of cascading aggregations:

Cascading aggregations

After the health of child elements are evaluated, the health sub-system evaluates the health of a parent entity based on the maximum percentage of unhealthy children configured at a specific level.
