Migrate Cassandra Databases to Cosmos DB

Migrating on-premises or self-hosted databases to the cloud can be daunting, especially when managing high-throughput Cassandra workloads. Transitioning to a fully managed cloud database like Cosmos DB offers scalability and lower maintenance, but it requires careful planning and execution. This text-based course guides you step-by-step through the entire migration lifecycle, showing you how to transition your workloads with confidence. You will learn how to map your existing Cassandra schemas, choose the right migration tools, and execute a transition that preserves data integrity and minimizes system downtime. By the end of this course, you will have a clear blueprint for moving database workloads to a modern, globally distributed environment. What you'll learn: - Understand the core architectural differences between native Cassandra and the Cosmos DB API for Cassandra - Plan your migration strategy using assessment tools to estimate throughput and storage needs - Map Cassandra data models and partition keys to optimized Cosmos DB structures - Execute live and offline migrations using tools like Spark, AzCopy, and the Cassandra SSTable loader - Implement modern security standards, including identity-based access control and encryption - Validate migrated data to ensure consistency and performance post-migration You will start with foundational database concepts and schema differences before moving into practical migration pathways and validation techniques. The material is structured to build your confidence through clear, written explanations and real-world architectural scenarios. This course is designed for database administrators, cloud engineers, and developers who are new to Cosmos DB. No prior cloud migration experience is required, though a basic understanding of Cassandra concepts is helpful. Start reading today to transition your Cassandra workloads to the cloud with confidence.
