Database Economics: Benchmarking Performance per Dollar ($/QPS) Across Modern Alternatives

An empirical comparison of PostgreSQL, ClickHouse, and Valkey against Oracle, Snowflake, and DynamoDB. Why switching cuts database bills by 70%.

Proprietary enterprise databases charge massive premiums on per-core licensing and managed IOPS. We ran systematic 10-million row read/write benchmarks comparing open modern alternatives against legacy stacks. The result: modern columnar and in-memory engines deliver 4.5x to 10.8x higher throughput per dollar ($/QPS).
