Amazon Simple Storage Service (S3) is a scalable object storage service offered by AWS that provides industry-leading durability, availability, performance, and security. S3 allows you to store and retrieve any amount of data from anywhere on the web, making it ideal for a wide range of use cases including backup and restore, disaster recovery, archives, data lakes, and static website hosting. S3 stores data as objects within buckets. An object consists of a file (of any format) and optional metadata. Buckets are containers for objects and have a globally unique name. S3 offers different storage classes optimized for various use cases: S3 Standard for general-purpose storage, S3 Intelligent-Tiering for automatic cost optimization, S3 Standard-IA and S3 One Zone-IA for infrequent access, S3 Glacier and S3 Glacier Deep Archive for long-term archival. S3 provides robust security features including bucket policies, IAM policies, access control lists (ACLs), encryption (SSE-S3, SSE-KMS, SSE-C, and client-side), and VPC endpoints. Data integrity is verified through checksums, and versioning helps protect against accidental deletion or overwrite. S3 offers features like lifecycle policies to automatically transition objects between storage classes or expire them, event notifications to trigger workflows, cross-region replication for compliance or latency requirements, transfer acceleration for fast uploads, multipart uploads for large files, and S3 Select for efficient querying. S3 integrates seamlessly with other AWS services such as CloudFront for content delivery, Lambda for serverless computing, and AWS Data Pipeline for data processing workflows. With its pay-as-you-go pricing model, high durability (99.999999999%), and virtually unlimited scalability, S3 is a foundational service in many AWS architectures.
