Knowledge of Dropbox and Amazon S3

Dropbox is a file hosting service that can help sync files between computers and mobile devices to bring files, photos and videos anywhere and share them with others easily. It's compatible with Mac, Windows and Linux system. Moreover, you are able to access to the latest version of every file. As such, if you have updated a document through your phone, you can download the same document via your computer.

Amazon S3, whose full name is Amazon Simple Storage Service, is a fully redundant data storage system. S3 makes it easy to store and retrieve any amount of data at anytime from anywhere. It can be employed to store any type of object which allows for uses like storage for Internet applications, backup and recovery, disaster recovery, data archives, data lakes for analytics, and hybrid cloud storage.
