S3
Amazon S3 (Simple Storage Service) is a scalable object storage service offered by Amazon Web Services (AWS) that allows users to store and retrieve any amount of data from anywhere on the web. It is designed for 99.999999999% durability and provides features like versioning, lifecycle policies, and encryption to manage data efficiently. S3 is commonly used for backup, archiving, data lakes, static website hosting, and as a storage backend for applications.
Developers should learn and use S3 when building cloud-native applications that require scalable, durable, and secure storage for unstructured data such as images, videos, logs, or backups. It is essential for use cases like hosting static websites, enabling data analytics through integration with services like AWS Glue or Athena, and serving as a cost-effective solution for long-term data retention with its tiered storage classes (e.g., S3 Standard, S3 Glacier).
