Chat says answer C - A isn’t supported (CloudWatch Logs can’t stream directly to OpenSearch). B (Lambda) adds code/ops you don’t need. D requires installing agents on servers and using Data Streams—unnecessary overhead.
In summary, the CloudWatch Logs → Kinesis Data Firehose → Amazon OpenSearch Service (option C) integration is the path recommended by AWS for this type of case. It allows for near real-time transmission, automatic scaling and relatively simple configuration, with the lowest operational overhead .
CloudWatch Logs subscription filter: This is the most straightforward way to stream logs from a CloudWatch Logs group to Amazon OpenSearch Service (Amazon Elasticsearch Service) in near real-time. It eliminates the need for additional components or complex configurations, reducing operational overhead. Direct integration: CloudWatch Logs can directly stream logs to OpenSearch Service without requiring intermediate services, making it a simple and efficient solution. Low operational overhead: Once set up, the subscription filter automatically forwards logs to OpenSearch Service with minimal maintenance.
