What is AWS PrivateLink?

AWS PrivateLink is a highly available, scalable technology that you can use to privately connect your VPC to services and resources as if they were in your VPC. You do not need to use an internet gateway, NAT device, public IP address, AWS Direct Connect connection, or AWS Site-to-Site VPN connection to allow communication with the service or resource from your private subnets. Therefore, you control the specific API endpoints, sites, services, and resources that are reachable from your VPC.

Use cases

You can create VPC endpoints to connect clients in your VPC to services and resources that integrate with AWS PrivateLink. You can create your own VPC endpoint service and make it available to other AWS customers. For more information, see AWS PrivateLink concepts.

In the following diagram, the VPC on the left has several Amazon EC2 instances in a private subnet and five VPC endpoints - three interface VPC endpoints, a resource VPC endpoint and a service-network VPC endpoint. The first interface VPC endpoint connects to an AWS service. The second interface VPC endpoint connects to a service hosted by another AWS account (a VPC endpoint service). The third interface VPC endpoint connects to an AWS Marketplace partner service. The resource VPC endpoint connects to a database. The service network VPC endpoint connects to a service network.

Connect to an AWS service, an endpoint service in another AWS account, or a partner service.
Learn more

You can create, access, and manage VPC endpoints using any of the following:

  • AWS Management Console — Provides a web interface that you can use to access your AWS PrivateLink resources. Open the Amazon VPC console and choose Endpoints or Endpoint services.

  • AWS Command Line Interface (AWS CLI) — Provides commands for a broad set of AWS services, including AWS PrivateLink. For more information about commands for AWS PrivateLink, see ec2 in the AWS CLI Command Reference.

  • AWS CloudFormation - Create templates that describe your AWS resources. You use the templates to provision and manage these resources as a single unit. For more information, see the following AWS PrivateLink resources:

  • AWS SDKs — Provide language-specific APIs. The SDKs take care of many of the connection details, such as calculating signatures, handling request retries, and handling errors. For more information, see Tools to Build on AWS.

  • Query API — Provides low-level API actions that you call using HTTPS requests. Using the Query API is the most direct way to access Amazon VPC. However, it requires that your application handle low-level details such as generating the hash to sign the request and handling errors. For more information, see AWS PrivateLink actions in the Amazon EC2 API Reference.
