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 Azure Load Balancer

Azure Load Balancer allows you to distribute traffic across VMs, allowing you to scale apps by distributing loads and offering high availability so that in the event a node becomes unhealthy, traffic is not sent to us.

Load balancers distribute traffic and manage the session persistence between nodes in one of two ways:

  • The default is Five-tuple Hash. The tuple is composed of the source IP, source port, destination IP, destination port, and protocol type. Because the source port is included in the hash and the source port changes for each session, clients may use different VMs between sessions. This means that applications that need to maintain state for a client between requests will not work.
  • The alternative is Source IP Affinity. This is also known as session affinity or client IP affinity. This mode uses a two-tuple hash (from the source IP address and destination IP address) or three-tuple hash (from the source IP address, destination...
