What Is AWS S3?
Amazon S3 (Simple Storage Service) is like a giant online locker where you can safely store your files, from photos and documents to entire application backups. It’s a cloud-based storage service designed for speed, durability, and easy access—whenever you need your data, it’s there, ready to go.
Whether you’re building a mobile app, backing up a website, or storing user-generated content, S3 gives you a flexible and scalable solution without needing to manage physical hardware.
