Amazon S3 is a highly durable and distributed data store. Using a web services interface, you can store and retrieve large amounts of data as objects in buckets (containers). The stored objects are also accessible from the web via HTTP. It supports the implementation of stringent security and compliance policies on the stored data to ensure the security of data-at-rest. S3 is also an economical storage option for massive amounts of data typically used by analytics, IoT, and machine learning applications.
