title: Connecting to AWS Neptune
body: <p>In the official aws neptune documentation they have mentioned that we can connect to neptune outside vpc but a security group has to be defined for that. Though somewhere it is mentioned that you cannot connect to it from outside vpc and if want to connect then it is only possible through EC2. 
  So now I am a bit confused and want to know can we connect to AWS Neptune from outside VPC but not through EC2 via a Java application running on any server or local? </p>
