Aiven has released benchmark figures comparing the performance of PostgreSQL 13.4 on Amazon Web Services (AWS), Google Cloud Platform (GCP) and Microsoft Azure across four different plans. The benchmarks measured write performance metrics by scaling up nodes vertically while keeping the number of nodes constant. Results showed that overall, the performance/cost difference between cloud providers favored Google. Aiven recommends users to identify performance bottlenecks and tune their database configuration, workload or hardware settings for optimal results.
