AWS S3 (Simple Storage Service) is a scalable object storage service offered by Amazon Web Services. It allows you to store and retrieve any amount of data, at any time, from anywhere on the web. S3 provides high durability, availability, and security for your data.
With S3, you can create and manage buckets (containers) to store your objects (files). Each object in S3 is uniquely identified by a key (file name) and is stored in a bucket. You can use S3 to store various types of data such as documents, images, videos, backups, and more.
S3 offers features such as versioning, cross-region replication, lifecycle management, encryption, access control, event notifications, and more. It integrates well with other AWS services, making it a popular choice for storing and serving static files, hosting static websites, backup and restore, data archiving, and content distribution.
