Hi spykid ,

You cannot create the VPC endpoint directly in Appian; only Appian Support can perform this.
Initiate the process by providing your AWS VPC endpoint service information to Appian via a support ticket.

Although for reference, you can follow the below steps:

1. Prepare Your AWS VPC Endpoint Service
In your AWS account, set up a VPC endpoint service (powered by AWS PrivateLink) attached to a Network Load Balancer (NLB) that routes traffic to your RDS instance. Grant Appian’s AWS principals permission to connect to your VPC endpoint service.

2. Provide Details to Appian
Supply Appian Support with the service name of your AWS PrivateLink endpoint service (e.g., com.amazonaws.region.vpce-svc-xxxxxxxxx). Provide any required IAM roles, principal ARNs, and network information for access.

3. Appian Support Creates VPC Endpoint
Appian will create a VPC endpoint in their cloud environment that connects to your provided VPC endpoint service. This process is managed by Appian; you need to open a support ticket with your endpoint service details. Appian will inform you once the endpoint creation and connectivity are complete.

4. DNS and Endpoint Configuration
Appian provides an endpoint-specific DNS hostname for use in Appian Cloud. Configure your integrations to reference this hostname for database connections.

5. Maintenance and Testing
Appian will work with you to schedule any required maintenance windows or connectivity tests in lower environments before going to production.

Yes.

But the response is quite slow and it seems like they are misunderstanding what I want to ask.

So to get more general awareness about privateLink settings, I am trying to get more information from real example

Did you contact Appian support before asking here?

Hi, spykid

I also want to access an AWS Aurora datasource via PrivateLink.
Did you succeed in doing this?

It says: "... Appian Support will work with you ...". Open a support ticket and they will help you.
