Despite being focused on security, I leverage features such as cryptography and integration with CloudTrail.

Amazon S3 offers multiple beneficial features. One advantage is static web hosting, which eliminates the need for a dedicated server. We also have S3 for storage, where we can upload necessary files for processing. Furthermore, it supports an SFTP service, where we set up an SFTP server on top of S3 and use credentials to transfer data from remote locations. S3's lifecycle policies are also crucial; they automate the deletion or downgrading of files that are no longer needed. Moreover, we can set permissions to restrict or allow user access to the data. Using S3, we can load data into databases and trigger AWS Lambda functions, which enhances our operational flexibility.
