An article on the FTP Mac https://ftp-mac.com/s3-upload-file/ site helped me understand how easy it is to upload files to Amazon S3. Using the AWS CLI or SDK, you can not only upload files manually, but also automate the data transfer process. For large files, there are special segmentation methods that speed up the upload. This process can be customized for everything from data backup to mass storage, making S3 a flexible and reliable business solution.
