A company needs to deliver a continuous stream of application events to S3. It can tolerate buffering for a few minutes and wants optional managed transformation before delivery. It does not need custom per-record consumers or replay from the delivery service. Which option has the least stream-delivery administration?

1. An SQS FIFO queue that writes each received message to S3 automatically without any consumer.
2. Use Kinesis Data Streams and write and operate a custom consumer application that batches and uploads records to S3.
3. A self-managed Kafka cluster on EC2 plus custom brokers, connectors, and patching scripts.
4. Amazon Data Firehose with an S3 destination and an optional supported transformation configuration.
