Ask HN: $5 MySQL / PostgreSQL Instances [Idea]?

Would you use shared mysql/postgres instances to lower the cost of your side hustle database costs?

How it would work:

- pool 5-10 people together to share a DB instance - only allow access to the IPs those 5-10 people need - each person can only see their tables - instances would be hosted on GCP (Google)

Why:

- Hosted mysql instances can get damn expensive
