This technical report presents a benchmark analysis comparing OVHcloud's PostgreSQL Database as a Service (DBaaS) against AWS RDS PostgreSQL, Azure Flexible PostgreSQL, and DigitalOcean PostgreSQL. The study evaluates performance and cost using widely recognized OLTP workloads, specifically the Yahoo! Cloud Serving Benchmark (YCSB) and a TPC-C workload. The methodology includes a detailed examination of throughput, latency, and overall cost efficiency across equivalent instance types. Results indicate that OVHcloud PostgreSQL delivers competitive performance, often surpassing its competitors in throughput while maintaining a strong price-performance ratio. The analysis highlights the implications of selecting a DBaaS provider on both performance metrics and budget considerations. The report also includes a comprehensive cost analysis, detailing instance, storage, and IOPS costs for each service. The findings are intended for engineering and product teams to inform decisions regarding database service provider selection in the context of the 2025 PostgreSQL DBaaS market.
