Amazon OpenSearch Serverless now available in AWS US West (N. California) and Europe (Stockholm) Regions

We are excited to announce that [Amazon OpenSearch Serverless](https://aws.amazon.com/opensearch-service/features/serverless/) is expanding availability to AWS US West (SFO, N. California) and Europe (ARN, Stockholm) Regions. OpenSearch Serverless is a serverless deployment option for Amazon OpenSearch Service that makes it simple to run search and analytics workloads without the complexities of infrastructure management. OpenSearch Serverless’ compute capacity used for data ingestion, search, and query is measured in OpenSearch Compute Units (OCUs). To control costs, customers can configure maximum number of OCUs per account.
