VpcConfiguration

The ARN of the IAM role that you want the Firehose stream to use to create endpoints in the destination VPC. You can use your existing Firehose delivery role or you can specify a new role. In either case, make sure that the role trusts the Firehose service principal and that it grants the following permissions:

The IDs of the security groups that you want Firehose to use when it creates ENIs in the VPC of the Amazon OpenSearch Service destination. You can use the same security group that the Amazon OpenSearch Service domain uses or different ones. If you specify different security groups here, ensure that they allow outbound HTTPS traffic to the Amazon OpenSearch Service domain's security group. Also ensure that the Amazon OpenSearch Service domain's security group allows HTTPS traffic from the security groups specified here. If you use the same security group for both your delivery stream and the Amazon OpenSearch Service domain, make sure the security group inbound rule allows HTTPS traffic. For more information about security group rules, see Security group rules in the Amazon VPC documentation.

The IDs of the subnets that you want Firehose to use to create ENIs in the VPC of the Amazon OpenSearch Service destination. Make sure that the routing tables and inbound and outbound rules allow traffic to flow from the subnets whose IDs are specified here to the subnets that have the destination Amazon OpenSearch Service endpoints. Firehose creates at least one ENI in each of the subnets that are specified here. Do not delete or modify these ENIs.
