Amazon Simple Storage Service Bucket Icon

Amazon Simple Storage Service (S3) buckets are like online file cabinets in the cloud. You can store any type of file in them, from images and videos to databases and software code. They're incredibly scalable, meaning you can store massive amounts of data, and highly durable, designed to protect your files from loss. S3 is primarily used for storing and retrieving data easily and cost-effectively, offering different access control options to manage who can view and modify your files.
