Amazon S3
Amazon Simple Storage Service (S3) provides highly scalable, secure, and durable object storage. It is designed for low-cost and large capacity provision across multiple geographical regions.
What is object storage? It's simply persistence of data in the form of objects-- which are files bundled with the raw data, metadata, and a unique identifiers. Picture photos, songs in mp3 format, or PDFs. In Amazon S3, there is a fundamental entity called Object which contains metadata, key, etc.
On a security level, Amazon S3 has both Client-Side and Server-Side encryption to make data secure and it also maintains multiple copies of the data for regeneration in case of data corruption. Hence, for instance, if S3 detects corruption in data, it will immediately repair it with replicated data.
