What is Amazon S3?

Amazon S3 (Simple Storage Service) is a cloud storage service provided by Amazon Web Services (AWS). It allows users to store and retrieve any amount of data, at any time, from anywhere on the web. S3 provides high durability and availability for data, making it suitable for storing mission-critical data. S3 can be used for a variety of use cases, including data archiving, backups, big data analytics, and disaster recovery.

Amazon S3 has several types of storage classes designed to meet different data storage and access needs:

  1. S3 Standard: general-purpose storage for frequently accessed data with high durability.
  2. S3 Intelligent-Tiering: automatically moves data to the most cost-effective access tier.
  3. S3 Standard-IA (Infrequent Access): lower-cost storage for data that is accessed less frequently.
  4. S3 One Zone-IA: lower-cost storage for infrequently accessed data, with a single availability zone for data redundancy.
  5. S3 Glacier: extremely low-cost storage for data archiving and long-term retention.
  6. S3 Glacier Deep Archive: the lowest-cost storage option for data that may be needed once or twice a year.

Each storage class is designed to cater to specific use cases and has different performance characteristics, pricing models, and retrieval times.
