Given a VPC, can I not explicitly mention which subnets the RDS instance should exist?
I have created a VPC 10.0.0.0/24 with three subnets as shown below:
REST servers - 10.0.0.0/25
RDS - AZ1 - 10.0.0.128/26
RDS - AZ2 - 10.0.0.192/26
When creating the DB, I am able to provide the VPC name. It seems, all subnets of this VPC are automatically selected. I am not able to specify the two subnets (as shown in the list above). There is an option for public accessibility which I have set to No. Therefore, even though all subnets seem to be applied for this RDS instance, it seems that, it will be accessible only from the REST servers subnet.
