DB Instance Class for PostgreSQL RDS instance on AWS

Hi, could you let me know which DB instance class to select when setting up Survey Solutions on Amazon AWS. On the set up guide, we do have the server requirements for EC2 instance (Hardware: CPU: 4 physical cores, 64-bit, RAM: 16GB and DISK: 500GB SSD) but we don’t have one for RDS DB instance class? Does anyone know which one to select?

What you’ve cited above is the minimal requirements, actual requirements will vary of course.

The advantage of setting a server in the cloud is that you can re-scale your installation relatively painlessly, if it is found inadequate, for example, for AWS refer to: Modifying an Amazon RDS DB instance - Amazon Relational Database Service

Thanks for your help.
