Which AWS service is designed to transfer data between AWS storage services?

AWS DataSync is a data transfer service that simplifies, automates, and accelerates moving data between on-premises storage systems and AWS storage services, as well as between different AWS storage services. It's specifically designed for large-scale data migrations and recurring data transfers. AWS Direct Connect provides a dedicated network connection from your premises to AWS, which is for network connectivity, not a data transfer service itself. AWS Lake Formation is a service that helps build, secure, and manage data lakes, not primarily a data transfer mechanism between existing storage services. Amazon S3 is an object storage service and while data can be moved into and out of it, S3 itself isn't the service designed to orchestrate transfers between different storage services.
