AWS Simple Storage Service (S3)

Amazon Simple Storage Service (S3) is a web storage service to store/retrieve images, videos, documents, executables, or any other kind of data centrally over the internet. S3 is accessed via the HTTP protocol using a web service interface which helps developers to create applications that are highly scalable, efficient, secured, and inexpensive. Data is managed as objects, so the storage system is called an object store.  Amazon also provides a backup and archiving store called Glacier. Storing data on Amazon Glacier costs less than storing data on Amazon S3. Conversely, retrieving data from Amazon Glacier takes up to 5 hours, compared to immediate access from Amazon S3.  To access S3 you can use the Management Console, the CLI, SDKs, or third-party tools like WinSCP, Putty etc...
