Amazon S3 (Simple Storage Service) is the world's most widely used cloud object storage platform, designed for virtually unlimited scalability, 99.999999999% durability, and fine-grained access controls. Organizations of all sizes use S3 to store, manage, and protect data for use cases ranging from data lakes and mobile applications to backup and analytics.

For dotCMS customers, S3 serves as a natural home for media assets, uploaded files, backups, and archived content — particularly in headless or multi-channel architectures where assets need to be served globally at low latency. Because dotCMS Cloud already runs on AWS infrastructure, S3 integrates natively into the content delivery pipeline, and self-hosted customers can connect S3 as an external storage layer for assets and static files.
