Last updated on February 16, 2024

  S3 Standard S3 Standard-Infrequent Access (IA) S3  One Zone – Infrequent Access (IA) S3 Intelligent Tiering S3 Express One Zone
Features General-purpose storage of frequently accessed data. For long-lived, rapid but less frequently accessed data; data is stored redundantly in multiple AZs. For long-lived, rapid but less frequently accessed data; data is stored redundantly in only one AZ of your choice. For long-lived data that have unpredictable access patterns. High performance storage for most frequently accessed data.

Storage transition S3 Standard to all other S3 storage types, including Glacier S3 Standard-IA to S3 One Zone-IA or S3 Glacier S3 One Zone-IA to S3 Glacier S3 Intelligent to S3 One Zone-IA or S3 Glacier You can either upload new objects directly or copy data from other storage classes.
Use cases Cloud applications, dynamic websites, content distribution, mobile and gaming applications, and big data analytics. Ideally suited for long-term file storage, older sync and share storage, and other aging data. For infrequently-accessed storage, like backup copies, disaster recovery copies, or other easily recreatable data. Data with unknown or changing access patterns, optimize storage costs automatically, and unpredictable workloads. For most frequently accessed data.

Additional Notes:

  • Data stored in the S3 One Zone-IA storage class will be lost in the event of AZ destruction.
  • S3 Standard-IA costs less than S3 Standard in terms of storage price, while still providing the same high durability, throughput, and low latency of S3 Standard.
  • S3 One Zone-IA has 20% less cost than Standard-IA.
  • Tutorials dojo strip
  • It is recommended to use multipart upload for objects larger than 100MB.
