Amazon S3 (Simple Storage Service) utilizes HTTP and HTTPS protocols for data transfer. These protocols are the foundation of data communication on the web, making them ideal for uploading and downloading objects stored in S3. HTTP is suited for general data transfer, while HTTPS provides secure data transfer by enabling encryption, thereby ensuring the confidentiality and integrity of data being transferred.

Using HTTP/HTTPS allows S3 to integrate seamlessly with web-based applications and services, making it easy for developers to work with storage in a manner that is both secure and efficient. This facilitates operations such as listing bucket contents, creating and deleting objects, and managing permissions over the network.

Other protocols listed do not serve the same function in the context of S3. For instance, FTP is primarily used for transferring files over a network but does not integrate with the web's RESTful API as effectively as HTTP/HTTPS. SSH is focused on secure remote access and command execution, while SMTP is a protocol for sending and receiving email. None of these are relevant for managing or accessing data within Amazon S3 directly.
