AWS IoT SiteWise and interface VPC endpoints (AWS PrivateLink)

You can establish a private connection between your virtual private cloud (VPC) and AWS IoT SiteWise by creating an interface VPC endpoint. Interface endpoints are powered by AWS PrivateLink, a technology that you can use to privately access AWS IoT SiteWise API operations without an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Instances in your VPC don't need public IP addresses to communicate with AWS IoT SiteWise API operations. Traffic between your VPC and AWS IoT SiteWise doesn't leave the AWS network.

Each interface endpoint is represented by one or more elastic network interfaces in your subnets.

For more information, see Interface VPC endpoints (AWS PrivateLink) in the Amazon VPC User Guide.

Considerations for AWS IoT SiteWise VPC endpoints

Before you set up an interface VPC endpoint for AWS IoT SiteWise, review the Interface endpoint properties and limitations in the Amazon VPC User Guide.

AWS IoT SiteWise supports making calls to the following AWS IoT SiteWise API operations from your VPC:

Creating an interface VPC endpoint for AWS IoT SiteWise

You can create a VPC endpoint for the AWS IoT SiteWise service. You can use either the Amazon VPC console or the AWS Command Line Interface (AWS CLI). For more information, see Creating an interface endpoint in the Amazon VPC User Guide.

Create a VPC endpoint for AWS IoT SiteWise by using one of the following service names:

  • For the data plane API operations, use the following service name: 

    com.amazonaws.region.iotsitewise.data

  • For the control plane API operations, use the following service name: 

    com.amazonaws.region.iotsitewise.api

Accessing AWS IoT SiteWise through an interface VPC endpoint

When you create an interface endpoint, we generate endpoint-specific DNS hostnames that you can use to communicate with AWS IoT SiteWise. The private DNS option is enabled by default. For more information, see Using private hosted zones in the Amazon VPC User Guide.

If you enable private DNS for the endpoint, you can make API requests to AWS IoT SiteWise through one of the following VPC endpoints.

  • For the data plane API operations, use the following endpoint. Replace region with your AWS Region.

    data.iotsitewise.region.amazonaws.com

  • For the control plane API operations, use the following endpoint. Replace region with your AWS Region.

    api.iotsitewise.region.amazonaws.com

If you disable private DNS for the endpoint, you must do the following to access AWS IoT SiteWise through the endpoint:

  • Specify the VPC endpoint url in API requests.

    • For the data plane API operations, use the following endpoint url. Replace vpc-endpoint-id and region with your VPC endpoint ID and Region.

      vpc-endpoint-id.data.iotsitewise.region.vpce.amazonaws.com

    • For the control plane API operations, use the following endpoint url. Replace vpc-endpoint-id and region with your VPC endpoint ID and Region.

      vpc-endpoint-id.api.iotsitewise.region.vpce.amazonaws.com

  • Disable host prefix injection. The AWS CLI and AWS SDKs prepend the service endpoint with various host prefixes when you call each API operation. This feature causes the AWS CLI and AWS SDKs to produce invalid URLs for AWS IoT SiteWise when you specify a VPC endpoint.

    Important

    You can't disable host prefix injection in the AWS CLI or the AWS Tools for PowerShell. This means that if you disable private DNS, then you can't use these tools to access AWS IoT SiteWise through the VPC endpoint. Enable private DNS to use the AWS CLI or the AWS Tools for PowerShell to access AWS IoT SiteWise through the endpoint.

    For more information about how to disable host prefix injection in the AWS SDKs, see the following documentation sections for each SDK:

For more information, see Accessing a service through an interface endpoint in the Amazon VPC User Guide.

Creating a VPC endpoint policy for AWS IoT SiteWise

You can attach an endpoint policy to your VPC endpoint that controls access to AWS IoT SiteWise. The policy specifies the following information:

  • The principal that can perform operations.

  • The operations that can be performed.

  • The resources on which operations can be performed.

For more information, see Controlling access to services with VPC endpoints in the Amazon VPC User Guide.

Example: VPC endpoint policy for AWS IoT SiteWise actions

The following is an example of an endpoint policy for AWS IoT SiteWise. When attached to an endpoint, this policy grants access to the listed AWS IoT SiteWise actions for the IAM user iotsitewiseadmin in AWS account 123456789012 on the specified asset.

{
    "Statement": [
        {
            "Action": [
                "iotsitewise:CreateAsset",
                "iotsitewise:ListGateways",
                "iotsitewise:ListTagsForResource"
            ],
            "Effect": "Allow",
            "Resource": "arn:aws:iotsitewise:us-west-2:123456789012:asset/a1b2c3d4-5678-90ab-cdef-33333EXAMPLE",
            "Principal": {
                "AWS": [
                    "123456789012:user/iotsitewiseadmin"
                ]
            }
        }
    ]
