Amazon S3

aws.amazon.com

Amazon S3 is an object storage service from Amazon Web Services. You pay for the objects you store, by storage class.[1][2]

Amazon Simple Storage Service (S3) is a highly scalable, secure, and durable object storage service offered by Amazon Web Services (AWS). It provides developers and IT teams with secure, durable, and highly-scalable cloud storage. S3 can store and retrieve any amount of data from anywhere on the web, making it ideal for a wide range of use cases including data lakes, websites, mobile applications, backup and restore, archive, enterprise applications, IoT devices, and big data analytics. S3 offers industry-leading scalability, data availability, security, and performance. It provides easy-to-use management features that allow you to organize data and configure finely-tuned access controls to meet specific business, organizational, and compliance requirements. With its integration capabilities with other AWS services and its comprehensive API, Amazon S3 has become a fundamental building block for many cloud-native applications and data storage solutions.

Rough guide, not a measurement: each description is written automatically from the site’s technology stack and the site has not confirmed it. A site is counted once, in the first group its description fits (shop, help and docs, blog, marketing site; otherwise the whole site). Descriptions that only guess (“likely”, “may”) are left out.
