Course Overview
The Microsoft course CosmosDB in a Day provides an accelerated, intermediate-level introduction to Azure Cosmos DB for NoSQL development, aligning with skills measured in the DP-3015 learning path and preparing developers for real-world cloud data challenges. Designed for software engineers, cloud developers, and application architects, this intensive training equips professionals with core competencies in non-relational data modeling, query execution, and resource configuration using the Cosmos DB SDK. With enterprise adoption of NoSQL databases on Azure growing over 40% between 2021 and 2024, demand for skilled practitioners continues to rise across industries deploying globally distributed applications.
Participants engage directly with key Microsoft technologies including Azure Cosmos DB for NoSQL, .NET SDK, JavaScript-based server-side programming, PowerShell, and the Azure Portal as the primary lab environment. Through hands-on exercises, students build functional components such as stored procedures, triggers, and user-defined functions while configuring databases, containers, and indexing policies. A central lab scenario involves creating a complete Cosmos DB resource hierarchy—from account provisioning to container deployment—and executing efficient SQL queries against JSON data, simulating real-world application integration tasks performed by cloud-native development teams.
This course supports preparation for the Microsoft Certified: Azure Cosmos DB Developer Specialty certification (exam DP-420), a credential recognized for validating expertise in designing and implementing scalable, high-performance data solutions on Azure. Certified professionals in the United States earn between $115,000 and $155,000 annually, reflecting strong market value.
