 {/* TODO: Write more about the advantages of RDS vs shared */}
+## RDS vs Shared DB
+- More Flavours: On AWS RDS we offer MySQL and MariaDB in addition to Postgres, while shared DB only offers Postgres or MongoDB.
+- Dedicated Instance: Each instance of AWS RDS is it's own dedicated instance.
+- Stability and Security: AWS RDS has greater stability due to it being a service directly offered by AWS, and also greater security due to being a dedicated instance.
+- Flexible: AWS RDS instances on the Shuttle platform can be customised to suit your needs. Instance size can be increased from the default and AWS RDS features can be enabled or disabled.
+
+The RDS instance created by Shuttle has the following specifications and features by default:
+- 2 vCPU
+- 1 GB Memory
+- 20 GiB Storage
+- Backups Disabled
+- Single Availability Zone
+- 1 Node
+- No Proxy
+
+The pricing of this instance can be found in the Pro Add-ons section of the [pricing page](https://www.shuttle.rs/pricing).
+
+If you require a different configuration, please contact us on [Discord](https://discord.gg/shuttle) or email us at [email protected]. We can provision any size or configuration of RDS to suit your needs - a full list of RDS features can be found [here](https://aws.amazon.com/rds/features/)
 
 Shuttle makes sure that any data stored in your provisioned database is stored permanently and will persist if you redeploy your server via `cargo shuttle deploy`, as well as if you restart your service via `cargo shuttle project restart`.
