Amazon RDS offers various databases, but there are limitations on what can and cannot be used in the free tier, so I’ve compiled them into a list. (as of 2017/08/19)

Filtering by "Free tier eligible only"

There’s a checkbox for “Free tier eligible only”, so you can check it to filter and confirm from the AWS console.

Databases Not Eligible for Free Tier

The AWS console politely states “Amazon Aurora is not eligible for the free tier.”

• All Amazon Aurora

• SQL Server Web
• SQL Server SE
• SQL Server EE

Databases Eligible for Free Tier

These are everything except the above, but I’ll list them just to be sure. It was surprising that all Oracle databases were eligible for the free tier.

• MySQL
• MariaDB
• PostgreSQL
• Oracle

Thoughts on AWS RDS Free Tier Eligibility

I’d like to try Amazon Aurora if possible, but I want to save money by taking advantage of the free tier, so I think I’ll use PostgreSQL.

That’s all from the Gemba.
