Which AWS service allows you to connect to storage from on-premise servers using standard file protocols?

AWS Storage Gateway is the service that enables on-premise servers to connect to cloud storage using standard file protocols. This service acts as a bridge between on-premises environments and AWS storage services, providing seamless integration and making it easier to manage data in both locations.

Storage Gateway supports various protocols, such as NFS (Network File System) and SMB (Server Message Block), allowing applications running on on-premise servers to access cloud storage as if it were local. This is particularly beneficial for businesses looking to leverage the scalability and cost-effectiveness of cloud storage while maintaining some operations on their local infrastructure.

In contrast, other services listed do not fulfill this specific role. For example, Amazon S3 is a scalable object storage service but does not directly interface with on-premise file protocols without an intermediary like Storage Gateway. Amazon RDS is focused on providing managed relational database services rather than file storage solutions, and AWS Lambda is a serverless compute service designed for running code without provisioning servers, which does not involve direct file protocol interactions.
