Amazon Aurora Pricing: The I/O-Optimized Crossover and the Serverless v2 ACU Trap
Aurora bills instance hours plus storage plus I/O, or storage at a 125% premium with I/O bundled (I/O-Optimized). Serverless v2 at $0.12 per ACU-hour wins on variable workloads, loses on steady traffic above roughly 2 ACU average. Global Database doubles the price per secondary region plus replicated-write fees. Backtrack adds per-change-record cost most teams never factor in.
