Creating a Virtual Private Cloud

A Vertica cluster on AWS must be logically located in the same network. This is similar to placing the nodes of an on-premises cluster within the same network. Create a virtual private cloud (VPC) to ensure the nodes in your cluster will be able to communicate with each other within AWS.

Create a single public subnet VPC with the following configurations:

• Assign a Network Access Control List (ACL) that is appropriate to your situation. The default ACL does not provide a high level of security.
• Enable DNS resolution and enable DNS hostname support for instances launched in this VPC.
• Add the required network inbound and outbound rules to the Network ACL associated to the VPC.

For more information about VPCs, including how to create one, see the AWS documentation.
