By: Sjoukje Zaal

Overview of this book

From designing solutions on Azure to configuring and managing virtual networks, AZ-300 certification can help you achieve all this and more. Whether you want to get certified or gain hands-on experience in administering, developing, and architecting Azure solutions, this study guide will help you get started. The book features not only the different exam objectives, but also guides you through configuring, managing, securing, and architecting Azure resources. Divided into five modules, this book will systematically take you through the different concepts and features as you advance through the sections. The first module demonstrates how to deploy and configure infrastructure. You will cover techniques related to implementing workloads and security, before learning how to create and deploy apps in the next module. To build on your knowledge, the final two modules will get you up to speed with implementing authentication, data security, and application and platform monitoring, along with covering Azure storage, alerting, and automation strategies. Finally, you’ll work through exam-based mock tests with answers to boost your confidence in passing the exam.

Understanding partitioning schemes

To meet the performance needs of your application, Azure Cosmos DB uses partitioning to scale individual containers in a database. Cosmos DB partitions in a way that the items are divided into distinct subsets called logical partitions. These are formed based on the value of the partition key that is added to each item in the container. All of the items that are in a logical partition have the same partition key. Each item in a container has an item ID (which is unique within the logical partition). To create the item's index, the partition key and the item ID are combined. This uniquely identifies the item.

If you look at our sample application from the previous section, you will see that the partition key and item ID are combined.

Besides logical partitions, Azure Cosmos DB also has physical partitions:

  • Logical partitions: A set of items that have the same partition key are called a logical partition. For instance, if you have a container that...
