Aiven for PostgreSQL has conducted a performance benchmarking comparison across four major cloud providers: AWS, GCP, OCI, and Azure. The benchmarks measured the transactions per second (TPS) of PostgreSQL instances on each provider, using similar configurations and varying database sizes. The results show that Aiven's managed PostgreSQL service outperforms the native services of the hyperscalers in terms of TPS and price. However, the performance difference is not always explicit in the overall pricing, making it essential to consider both factors when choosing a cloud provider for PostgreSQL. The benchmarks also highlighted the importance of considering latency and other network-related factors in evaluating database performance. Aiven plans to publish Terraform benchmarking scripts and extend the tests on a parameter settings level to provide more insights into performance improvements and comparisons with hyperscaler fork offerings.
