Implementing Microsoft Azure Architect Technologies: AZ-303 Exam Prep and Beyond - Second Edition

By: Brett Hargreaves, Sjoukje Zaal

Overview of this book

From designing solutions on Azure to configuring and managing virtual networks, the AZ-303 certification validates your knowledge and skills for all this and much more. Whether you want to take the certification exam or gain hands-on experience in administering, developing, and architecting Azure solutions, this study guide will help you get started. Divided into four modules, this book systematically takes you through the wide range of concepts and features covered in the AZ-303 exam. The first module demonstrates how to implement and monitor infrastructure. You'll develop the skills required to deploy and manage core Azure components such as virtual machines, networking, storage, and Active Directory (AD). As you progress, you'll build on that knowledge and learn how to create resilient and secure applications before moving on to working with web apps, functions, and containers. The final module will get you up to speed with data platforms such as SQL and Cosmos DB, including how to configure the different high availability options. Finally, you'll solve mock tests and assess yourself with the answers provided to get ready to take the exam with confidence. By the end of this book, you'll have learned the concepts and techniques you need to know to prepare for the AZ-303 exam and design effective solutions on Microsoft Azure.

Configuring high availability

Even when your databases are hosted in Azure, there is still a chance that failures and outages will occur. In the case of an outage (such as a total regional failure, which can be caused by a natural disaster, an act of terrorism, war, a government action, or a network or device failure external to the data centers of Microsoft), your data still needs to be accessible.

To create highly available SQL Server databases in Azure, you can use failover groups and active geo-replication, described in the following list:

  • Active geo-replication: Geo-replication is a business continuity feature that allows you to replicate the primary database and up to four read-only secondary databases in the same or different Azure regions. You can use the secondary databases to query data or for failover scenarios when there is a data center outage. Active geo-replication has to be set up by the user or the application manually.
  • Failover groups: Failover groups...
