Show HN: PostgreSQL performance and cost across 23 EC2 instance types

Hey! I'm Andrei.I got frustrated by how people tend to build overcomplicated backend systems, being "motivated" by big tech case studies and popular books.So, I started exploring lean architecture, and building my digital garden of ideas, approaches and data that align with this direction.Here I want to present one of the tools – Sizing tool for PostgreSQL. I've benchmarked PostgreSQL on different EC2 instances and disks, with different initial data sets to see performance that these instances can give you. And I've built a tool to visualize this data, which I welcome you to explore.So, you can put your usual input parameters, like needed RPS and disk size as input, and find out which instance will be the most cost-efficient for your needs.You can read about the methodology here: https://postgres.saneengineer.com/aboutI've tested one workload – mixed 90/10 read/write, and only selected configurations. But it is extensible, and I (and you – benchmark is open source: https://github.com/anivaniuk/sanebench) can run more configurations to have more data represented.Does it look interesting? What workload should I benchmark next?
