S3 aws guide

Amazon S3 is a highly scalable object storage service provided by AWS for storing and retrieving any amount of data from the web. S3 stores data as objects within buckets, where each object consists of data, a key, and metadata. While primarily object storage, S3 can support use cases involving block storage through integration with services like EBS. It provides unlimited storage capacity with a guaranteed durability of 99.999999999% and high availability. S3 offers various storage classes, including S3 Standard, Intelligent-Tiering, Standard-IA, One Zone-IA, Glacier, and Glacier Deep Archive, to optimize cost and performance. S3 Standard is designed for frequently accessed data, while Glacier is for archival data with longer retrieval times. S3 Transfer Acceleration enables fast and secure file transfers over long distances by leveraging Amazon CloudFront's edge locations. Data is sent to the nearest CloudFront edge location and routed to the S3 bucket over an optimized network path. Enabling Transfer Acceleration can be done through the AWS Management Console, using a special endpoint. This is especially beneficial for users transferring large files from distant geographic locations.
