The document discusses options for scaling relational database management systems (RDBMS). It describes scale-up vs scale-out approaches, and compares solutions like master-slave replication, sharding, and using scale-out databases. It provides details on ClustrixDB's scale-out architecture with shared-nothing storage and automatic data distribution. Benchmark results show ClustrixDB outperforming Aurora for throughput and latency on OLTP workloads as nodes are added.
