[FIXED] Accessing non-public RDS from Jupyter notebook hosted on AWS?

Issue

If I host a Jupyter Notebook on AWS (like this guide shows) will it possible for the notebook to access a non-public RDS database instance? Is there some additional setup to allow it to do so or would it just work?

Solution

Either both the EC2 instance will have to be in the same subnet with the RDS or there should be a route table entry allowing the communication. Also, the security group should be allowed to make egress calls to the RDS and the RDS resource policy should allow the security group.
