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

Replication and redundancy


In order to guarantee stability and high availability, the customer's data in Azure Storage is replicated constantly. The customer may choose between two replication options: either  storage within the same datacenter or to a second datacenter. Replication guards the user's data; in the case of hardware failures, the application is preserved. The use of a second datacenter provides security in the case of a catastrophic failure in the location of the primary datacenter. The process of replication warrants that the customer's storage account meets the SLA for storage.

There are four replication options between which the user can choose when creating an Azure Storage account.

Locally redundant storage (LRS)

LRS means that the data is held three times in a datacenter in a region. The LRS manages three copies of the customer's data to protect it from hardware failures. LRS does not protect workloads from the failure of a whole datacenter; it only replicates data within...
