AWS PrivateLink allows you to connect to S2 privately from your VPC, without exposing traffic to the public internet. You also benefit from reduced egress costs with private connectivity rates.

​
Setup

1

Get Service Name from S2 Dashboard

Go to the S2 dashboard, in the Basins tab, expand the Private Connectivity section to find your PrivateLink service name.
2

Navigate to VPC Endpoints

Search for VPC endpoint on the AWS console and select “Endpoints”.
3

Create Endpoint

Click on “Create Endpoint”.
4

Select Service Type

Select “PrivateLink Ready Partner Services”.
5

Verify Service

Enter the PrivateLink service name from the S2 dashboard and click on “Verify Service”.
6

Select VPC

Select the appropriate VPC.
7

Enable Private DNS

Enable private DNS name.
8

Include Subnets

Include subnets.
9

Configure Security Groups

Select appropriate Security Groups.
HTTPS (port 443) must be allowed in both inbound and outbound security group rules. Access can be left open to 0.0.0.0/0 or, preferably, restricted to the PrivateLink endpoint’s private IP address or CIDR range.

​
Validate Your Connection

  1. From a VM on your VPC, try resolving the S2 basin DNS record: 
    nslookup basin.b.aws.s2.dev
    You may need to clear caches or wait a few moments for this to take effect.
  2. If everything has worked, this DNS record should resolve to a private IPv4 address (e.g., starting with 10.*).
