Editing Amazon Simple Storage Service (S3)

[[wikipedia:Amazon S3]] ([[AWS timeline|2006]]) or Amazon Simple Storage Service a service offered by Amazon Web Services (AWS) since 2006 that provides [[Object Storage]] through a web service interface or CLI.

* [[AWS free tier]]: 5 GB

== Features ==
* [[Encryption]]
* [[AWS S3 replication|Replication]]
* [[AWS S3 lifecycle|Lifecycle]]
* [[AWS S3 versioning|Versioning]]
* [[Object tagging]]

== [[Amazon S3 Storage Classes]] ==
* Amazon S3 Standard is the default class.
* [[Amazon S3 Intelligent-Tiering]] ([[AWS timeline|Sep 2021]])<ref>https://aws.amazon.com/blogs/aws/amazon-s3-intelligent-tiering-further-automating-cost-savings-for-short-lived-and-small-objects/</ref>
* [[Amazon S3 Standard Infrequent Access (IA)]] is designed for less frequently accessed data. Typical use cases are backup and disaster recovery solutions.
* Amazon S3 One Zone-Infrequent Access is designed for data that is not often needed but when required, needs to be accessed rapidly. Data is stored in one zone and if that zone is destroyed, all data is lost.
* [[Amazon Glacier]] is designed for long-term storage of data that is infrequently accessed and where retrieval latency of minutes or hours is acceptable. "[[Glacier Deep Archive]]" is an alternative with a retrieval time of at least 12 hours, but 1/4th the price. It is intended as an alternative to magnetic tape libraries, and is designed for long term retention of data for 7 to 10 years.
