A company has deployed AWS Network Firewall in a VPC and needs to deliver Network Firewall flow logs to an Amazon OpenSearch Service cluster with the lowest possible latency. Which solution meets this requirement?

Kinesis Data Firehose is the most suitable option because it directly integrates with Network Firewall for log delivery and supports Amazon OpenSearch Service as a direct destination. This serverless approach minimizes latency and operational overhead for near real-time ingestion. The S3-SNS-Lambda solution introduces multiple hops and processing delays, increasing latency. Direct delivery to OpenSearch from Network Firewall is not a supported feature. While Kinesis Data Streams can be used, it requires a consumer application (like a Lambda function or an EC2 instance) to pull data and push it to OpenSearch, adding complexity and latency compared to Firehose's direct integration.
