Optimizing Performance and Cost for Amazon RDS & Aurora PostgreSQL at Scale

Modern Amazon RDS and Aurora PostgreSQL deployments must balance performance, reliability, and cost, especially at scale. In this session, we’ll explore practical strategies for improving database performance while simultaneously reducing infrastructure spend. We’ll cover right-sizing, modern instance adoption (including Graviton), storage and I/O optimization, benchmarking techniques, and observability-driven tuning. Based on real production experience, these approaches often lead to measurable performance gains and 20–50% cost reductions without compromising availability.
