High Availability and Disaster Recovery are significant motivations for transitioning from traditional RDBMS to NoSQL systems like Couchbase Server, which offers features tailored to these needs. A webinar demonstrated setting up multi-master, multi-region clusters and introduced a tutorial for replicating data between them, with a sample application using the Couchbase Multi-Cluster Aware client available on GitHub. The replication relies on Couchbase's Cross-Data Center Replication (XDCR) feature, with additional resources available for those interested in further exploration. Couchbase is open source, free to try, and supported by a variety of resources including a developer portal, forums, and active community engagement on platforms like Twitter and Stack Overflow.
