Amazon Simple Storage Service Bucket With Objects Icon

Amazon S3 (Simple Storage Service) provides cloud-based object storage. Imagine it as a massive, highly scalable file system in the cloud. You create buckets, which are like containers, and inside these buckets, you store objects, which can be any type of file (images, videos, documents, etc.). S3 is primarily used for storing and retrieving data, making it easy to access from anywhere with an internet connection. It's incredibly reliable, durable and cost-effective, making it a popular choice for various data storage needs, from backups and archives to serving websites and applications.
