Amazon OpenSearch Service expands cross-VPC connectivity to the AWS GovCloud (US) Regions
Amazon OpenSearch Service now offers support for managed VPC endpoints (powered by AWS PrivateLink) in two additional regions - AWS GovCloud (US-East), and AWS GovCloud (US-West). Managed VPC endpoints allow to connect to your Amazon OpenSearch Service VPC-enabled domain in a Virtual Private Cloud (VPC). With an Amazon OpenSearch Service managed endpoint, you can now privately access your OpenSearch Service domain within your VPC from your client applications in other VPCs, within the same or across AWS accounts, without using public IPs or requiring traffic to traverse the Internet.
With this release, OpenSearch Service allows you to create an endpoint to an OpenSearch Service domain from another VPC in the same account or in another AWS account. You can either use the OpenSearch Service console or OpenSearch Service APIs to create an OpenSearch Service managed VPC endpoint.
Amazon OpenSearch Service managed VPC endpoints are powered by AWS PrivateLink. If you use OpenSearch Service managed VPC endpoints to access your OpenSearch Service domain from your client applications in another VPC, you will incur standard AWS data transfer charges and the associated cost for the AWS PrivateLink interface endpoint.
Please refer to the AWS Region Table for more information about OpenSearch Service availability. For more information, including instructions on getting started with setting up cross-VPC connectivity, please refer the OpenSearch Service documentation.
