Amazon Timestream for InfluxDB API and interface VPC endpoints (Amazon PrivateLink)

You can establish a private connection between your VPC and Amazon Amazon Timestream for InfluxDB control plane API endpoints by creating an interface VPC endpoint. Interface endpoints are powered by Amazon PrivateLink. Amazon PrivateLink allows you to privately access Amazon Timestream for InfluxDB API operations without an internet gateway, NAT device, VPN connection, or Amazon Direct Connect connection.

Instances in your VPC don't need public IP addresses to communicate with Amazon Timestream for InfluxDB API endpoints. Your instances also don't need public IP addresses to use any of the available Timestream for InfluxDB API operations. Traffic between your VPC and Amazon Timestream for InfluxDB doesn't leave the Amazon network. Each interface endpoint is represented by one or more elastic network interfaces in your subnets. For more information on elastic network interfaces, see Elastic network interfaces in the Amazon EC2 User Guide.

After you create an interface VPC endpoint, if you enable private DNS hostnames for the endpoint, the default Timestream for InfluxDB endpoint (https://timestream-influxb.Region.amazonaws.com) resolves to your VPC endpoint. If you do not enable private DNS hostnames, Amazon VPC provides a DNS endpoint name that you can use in the following format:

VPC_Endpoint_ID.timestream-influxb.Region.vpce.amazonaws.com

For more information, see Interface VPC Endpoints (Amazon PrivateLink) in the Amazon VPC User Guide. Timestream for InfluxDB supports making calls to all of its API Actions inside your VPC.

Considerations for VPC endpoints

Before you set up an interface VPC endpoint for Amazon Timestream for InfluxDB API endpoints, ensure that you review Interface endpoint properties and limitations in the Amazon VPC User Guide. All Timestream for InfluxDB API operations that are relevant to managing Amazon Timestream for InfluxDB resources are available from your VPC using Amazon PrivateLink. VPC endpoint policies are supported for Timestream for InfluxDB API endpoints. By default, full access to Timestream for InfluxDB API operations is allowed through the endpoint. For more information, see Controlling access to services with VPC endpoints in the Amazon VPC User Guide.

Creating an interface VPC endpoint for the Timestream for InfluxDB API

You can create a VPC endpoint for the Amazon Timestream for InfluxDB API using either the Amazon VPC console or the Amazon CLI. For more information, see Creating an interface endpoint in the Amazon VPC User Guide.

After you create an interface VPC endpoint, you can enable private DNS host names for the endpoint. When you do, the default Amazon Timestream for InfluxDB endpoint (https://timestream-influxb.Region.amazonaws.com) resolves to your VPC endpoint. For more information, see Accessing a service through an interface endpoint in the Amazon VPC User Guide.

Creating a VPC endpoint policy for the Amazon Timestream for InfluxDB API

You can attach an endpoint policy to your VPC endpoint that controls access to the Timestream for InfluxDB API. The policy specifies the following:

	"Statement": [{
		"Principal": "*",
		"Effect": "Allow",
		"Action": [
			"timestream-influxb:CreateDbInstance",
			"timestream-influxb:UpdateDbInstance"		
		],
		"Resource": "*"
	}]
}
