# RDS

We are going to use [Aurora Serverless](https://aws.amazon.com/rds/aurora/serverless/). We will pay only for the resources we use and it will scale up or down automatically.

Search for `RDS` in `Services`:

Click `Databases` and `Create database`:

Scroll down and you find the "Serverless" option:

There are a few important limitations to the serverless version of Aurora:

* You can't give an Aurora Serverless DB cluster a public IP address. This means you can't access it from TablePlus (or similar) from your computer.
* The resources have to be in the same VPC to access the database (this is why we need the NAT).
* You can't turn on [Amazon RDS Performance Insights](https://docs.aws.amazon.com/en_pv/AmazonRDS/latest/AuroraUserGuide/USER_PerfInsights).
* It is compatible only with PostgreSQL version `10.7`. We need to reflect this to our local setup for development. `10.7` is not available on Docker Hub but `10` should work fine.\
  `docker run -e POSTGRES_PASSWORD=postgres -e POSTGRES_DB=bookapp -d -p 5432:5432 postgres:10`
