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.

Protecting VMs with Azure Backup

Part of ensuring a reliable service is the ability to back up and restore VMs. Single VMs can still become unavailable, corruption may occur, or they may get deleted accidentally.

Azure Backup allows you to create regular or one-off virtual backups, and the backups are replicated to a paired region, with the option to use locally redundant or zone-redundant replication. These options mean your backups would not be available in another region, but it costs less and is therefore a cost-effective solution for non-critical workloads.

It isn't just Azure VMs you can protect with Azure Backup. You can also back up the following:

  • On-premises VMs using the Microsoft Azure Recovery Services (MARS) agent
  • Azure File shares
  • SQL Server in Azure VMs
  • SAP HANA databases in Azure VMs
  • Azure Database for PostgreSQL servers

To enable backups on VMs, you need an Azure Recovery Services vault:
