Amazon S3

Amazon S3 is an object storage service that lets developers store and retrieve any amount of data with virtually unlimited scale. It automatically adjusts capacity as data is added or removed, so users only pay for the storage they actually use. The service offers multiple storage classes to balance cost and performance, and it provides APIs for managing objects, configuring lifecycle rules, and organizing data into buckets.

The platform is designed for high durability and availability, delivering 99.999999999 % durability and 99.99 % availability by default. Data is encrypted at rest and in transit, and fine‑grained access controls, logging, and compliance features help protect sensitive information and meet regulatory requirements.

Typical use cases include data lakes, backup and restore, archival, mobile and IoT applications, and serving assets for analytics, machine learning, and AI workloads. By offering a reliable, secure, and cost‑effective storage foundation, Amazon S3 supports a wide range of workloads for organizations of any size.
