Which AWS service is designed to ingest data from file systems?

AWS DataSync is designed specifically for transferring large amounts of data between on-premises storage systems and AWS storage services, such as Amazon S3 or Amazon EFS. It automates the process of moving data, allowing users to efficiently and securely ingest data from file systems into the cloud. DataSync simplifies the task of data ingestion by handling operations like bandwidth management and data validation, making it a suitable choice for users looking to synchronize files or migrate large datasets to AWS.

In contrast, while Amazon Glue is a data integration service primarily focused on preparing and transforming data for analytics, it does not directly handle the ingestion from file systems. Amazon S3 is a storage solution where data resides but does not inherently perform the ingestion process; rather, it serves as a destination for ingested data. Amazon Lambda is a compute service that allows the execution of code in response to events, but it is not specifically designed for data ingestion from file systems.
