Amazon 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 provides high durability, availability, and security for data storage, with features like versioning, lifecycle policies, and access controls. S3 is commonly used for backup, archiving, data lakes, static website hosting, and as a data source for big data analytics.
Developers should learn and use Amazon S3 when building cloud-native applications that require scalable, secure, and cost-effective storage for unstructured data, such as images, videos, logs, or backups. It is essential for scenarios like hosting static websites, enabling data sharing across distributed systems, or integrating with other AWS services like Lambda or Redshift for serverless computing and analytics. S3's pay-as-you-go pricing and global accessibility make it ideal for projects with variable or growing storage needs.
