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.

Implementing disaster recovery

Business-critical applications may have different backup and recovery requirements to servers that don't change often or store data. For applications that need to be recovered quickly, or that need to be backed up every few minutes or hours, Azure provides site recovery services.

Whereas Azure Backup takes a one-off backup at daily intervals, Azure Site Recovery continually replicates your VM's disks to another region. In the event that you need to failover, a new VM is created and attached to the replicated disk.

When determining a disaster recovery plan, two key points you need to consider are the following:

  • Recovery Time Object (RTO) – The maximum amount of elapsed time between a failure and having your service back and running.
  • Recovery Point Objective (RPO) – The maximum amount of data loss you are prepared to accept. If your data does not change very often, an RPO of 1 day may be sufficient, whereas for...
