Comparing to RDS

Pigsty is an AGPLv3-licensed, local-first RDS alternative that can be deployed on your own physical machines/virtual machines, or on cloud servers.

Therefore, we chose the world’s leading Amazon Cloud AWS RDS for PostgreSQL and China’s market leader Alibaba Cloud RDS for PostgreSQL as benchmarks.

Both Alibaba Cloud RDS and AWS RDS are proprietary cloud database services, offered only on the public cloud through a leasing model. The following comparison is based on the latest PostgreSQL 16 main branch version, with the comparison cut-off date being February 2024.

EC2	vCPU-Month	RDS	vCPU-Month
DHH’s self-hosted core-month price (192C 384G)	25.32	Junior open-source DBA reference salary	15K/person-month
IDC self-hosted data center (exclusive physical machine: 64C384G)	19.53	Intermediate open-source DBA reference salary	30K/person-month
IDC self-hosted data center (container, oversold 500%)	7	Senior open-source DBA reference salary	60K/person-month
UCloud Elastic Virtual Machine (8C16G, oversold)	25	ORACLE database license	10000
Alibaba Cloud Elastic Server 2x memory (exclusive without overselling)	107	Alibaba Cloud RDS PG 2x memory (exclusive)	260
Alibaba Cloud Elastic Server 4x memory (exclusive without overselling)	138	Alibaba Cloud RDS PG 4x memory (exclusive)	320
Alibaba Cloud Elastic Server 8x memory (exclusive without overselling)	180	Alibaba Cloud RDS PG 8x memory (exclusive)	410
AWS C5D.METAL 96C 200G (monthly without upfront)	100	AWS RDS PostgreSQL db.T2 (2x)	440

For instance, using RDS for PostgreSQL on AWS, the price for a 64C / 256GB db.m5.16xlarge RDS for one month is $25,817, which is equivalent to about 180,000 yuan per month. The monthly rent is enough for you to buy two servers with even better performance and set them up on your own. The rent-to-buy ratio doesn’t even last a month; renting for just over ten days is enough to buy the whole server for yourself.
