S3 – AWS’s object storage service.
Amazon S3, which has become the de facto standard for object storage in the cloud, is designed for storing and retrieving any amount of data from anywhere. It offers industry-leading durability (99.999999999%), different storage classes for cost optimization (Standard, Intelligent-Tiering, Standard-IA, One Zone-IA, Glacier), and comprehensive security features. S3 supports versioning, lifecycle policies, encryption, and fine-grained access controls. It integrates seamlessly with other services for data analytics, backup, and archiving. S3’s REST API has become so popular that other cloud providers often offer S3-compatible APIs for their object storage services. The service supports features like event notifications, cross-region replication, and transfer acceleration for optimized uploads.
