Amazon OpenSearch Ingestion now supports cross-account ingestion

Amazon OpenSearch Ingestion now supports cross-account ingestion for push-based sources such as HTTP and OpenTelemetry (OTel). With this launch, customers can easily share OpenSearch Ingestion pipelines across AWS accounts without relying on additional configurations like VPC peering or AWS Transit Gateway. This capability makes it simpler for organizations with multiple accounts to centralize observability and analytics workflows. For example, a central logging team can create ingestion pipelines and grant access to development teams across different accounts, enabling them to ingest logs, metrics, and traces directly into OpenSearch domains or OpenSearch Serverless collections. This reduces operational overhead and lowers the cost of sharing ingestion pipelines across accounts. Cross-account ingestion for Amazon OpenSearch Ingestion is available today in all AWS regions where OpenSearch Ingestion is [offered](https://docs.aws.amazon.com/general/latest/gr/opensearch-service.html#opensearch-service-regions). Customers can get started by creating resource policies in the AWS Management Console or using the AWS CLI, and then enabling pipeline endpoints from their VPCs to ingest data seamlessly. To learn more about this feature, see the [Amazon OpenSearch Service Developer Guide](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/cross-account-pipelines.html) and the launch [blog](https://aws.amazon.com/blogs/big-data/announcing-cross-account-ingestion-for-amazon-opensearch-service/).
