Amazon DynamoDB Pricing: The On-Demand vs Provisioned Crossover and the GSI Multiplier
DynamoDB on-demand bills $1.25 per million writes and $0.25 per million reads — pay-per-request convenience with no capacity planning. Provisioned at $0.00065/WCU-hour wins on steady traffic above ~50% utilization. Every GSI doubles the write cost, IA tier cuts storage 60% but adds 25% to request fees, and Global Tables compound the bill per region.
