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

Azure SQL Database business continuity


You now have your database up and running in the cloud, and you can even connect to it, and create, delete, and update the tables as you wish.

In this section, you will learn how to build a highly available and business continuity database.

How business continuity works in Azure SQL Database

Microsoft does its best to address any issues that may occur in Azure SQL Database, and it provides solutions to the following issues.

 

Hardware failure

Hardware failure is something that is expected to happen, but it will not be the reason that you lose your databases.

Just as replication is provided for storage, there is a similar safeguard for Azure SQL Databases.

If hardware failure occurs, there are three copies of your database, separated across three physical nodes. The three copies consist of one primary replica and two secondary replicas, and, to avoid any data loss, write operations are not committed in the primary replica until they have been committed to one...
