This course teaches developers how to build cloud-native applications using Azure Cosmos DB and its SQL API. Learners will gain practical experience designing, developing, and optimising applications that store and retrieve data using one of Microsoft's most scalable, globally distributed database platforms. Throughout the course, delegates will learn how to work with Azure Cosmos DB using SDKs and development tools, create efficient queries, implement indexing strategies, manage throughput and provision resources effectively. The course also covers data modelling, performance optimisation, security and best practices for developing modern applications that leverage NoSQL database technologies. Through a combination of instructor-led learning, practical exercises and real-world scenarios, learners will gain the skills required to build high-performing applications that integrate with Azure Cosmos DB and prepare for the Microsoft Azure Cosmos DB Developer Speciality (DP-420) certification exam.
