You will learn how to build globally distributed, low-latency applications using Azure Cosmos DB. The course covers basic and advanced concepts, including containers, documents, partitions, indexing, and server-side programming.

This course, sequentially structured, starts with the fundamental concepts of Cosmos DB and then explores advanced topics. Next, you will learn how to optimize query performance, reduce costs, and monitor and troubleshoot Cosmos DB. By the end of the course, you will be able to design and implement scalable Cosmos DB databases and manage resources using Azure CLI and the .NET SDK.

Upon completing the course, you’ll have the skills to build cloud-native applications that can handle the most demanding workloads and serve users around the world. You’ll also have hands-on experience with optimizing query performance, reducing Cosmos DB costs and monitoring and troubleshooting Cosmos DB.
