An application running on Amazon EC2 instances across multiple Availability Zones must ingest real-time data from third-party applications and place the raw ingested data into an Amazon S3 bucket. Which solution meets these requirements?

This solution correctly leverages Amazon Kinesis Data Streams for real-time data ingestion, which is designed for high-throughput, real-time processing of streaming data. Kinesis Data Firehose then reliably delivers this streaming data to Amazon S3, handling batching, compression, and encryption automatically. This combination is ideal for ingesting real-time data from multiple sources and efficiently storing it in S3. AWS DMS is for database migrations, not real-time data ingestion from applications. AWS DataSync is for large-scale data transfer between on-premises storage and AWS, or between AWS storage services, not real-time application ingestion. AWS Direct Connect provides a dedicated network connection but doesn't handle real-time data ingestion and delivery to S3; Kinesis Data Firehose can consume direct PUT operations but the primary ingestion mechanism for real-time streaming from applications is Kinesis Data Streams.
