Learn Data Centers and Nodes in Apache Cassandra by understanding how distributed architecture is built to ensure scalability, fault tolerance, and high availability. This training covers the role of nodes in storing and replicating data across the cluster. It also explains how data centers are organized to improve performance, reduce latency, and support geographic distribution. You will learn how Cassandra distributes data using replication strategies and consistent hashing. The course focuses on designing resilient cluster architectures that maintain performance and availability even during node or data center failures.
