​
Connecting to your VPC using AWS PrivateLink

AWS PrivateLink provides private connectivity between virtual private clouds (VPCs), supported services and resources, and your on-premises networks, without exposing your traffic to the public internet. To set up a PrivateLink connection between Cube Cloud Dedicated Infrastructure and your own VPC, you’ll need to prepare an Endpoint Service, share service details with the Cube team, and accept the incoming connection request.

​
Preparing the Endpoint Service

There are two common scenarios for preparing the Endpoint Service:
  • Connecting to a service in your AWS infrastructure
  • Connecting to a service provided by a third party such as Snowflake, Databricks, Altinity Cloud, etc.
In the case of your own infrastructure, please follow the official AWS documentation to configure the Endpoint Service pointing at your data source. If your data source is hosted in a third-party infrastructure, please follow the vendor’s documentation for creating and managing an Endpoint Service.

​
Allowing Cube Cloud Principal

Cube Cloud needs to be added to the list of principals allowed to discover your Endpoint Service. To do so, please go to AWS Console -> VPC -> Endpoint Services -> Your service -> Allow principals and add arn:aws:iam::331376342520:root to the list.

​
Gathering required information

To request establishing a PrivateLink connection, please share the following information with the Cube team:
  • Service Name (such as com.amazonaws.vpce.us-west-2.vpce-svc-abcde)
  • Reference Name for the record (such as “Snowflake-prod” or “clickhouse-dev”)
  • Ports: a list of ports that will be accessed through this connection
  • DNS Name (optional): an internal DNS name of the upstream service in case SSL needs to be supported
  • Dedicated Infrastructure Region: VPC Peering requires Cube to be hosted in dedicated infrastructure. Please specify what region the Cube Cloud dedicated infrastructure should be hosted in.
If a DNS name is provided, an internal DNS record will be created pointing at the established PrivateLink connection, and the service will be addressable by that name inside the Cube Cloud infrastructure.

​
Accepting the connection

The Cube Cloud team will notify you once the connection request is sent. You can accept it by going to AWS Console -> VPC -> Endpoint Services -> Your Service -> Endpoint Connections and clicking Accept Connection Request.

​
Using the connection

Once the connection is established, you can access your data source by addressing it either via the supplied DNS Name or an AWS internal DNS name returned to you by the Cube team.
